Overview

Arcanox is a top-down action-RPG dungeon crawler. Pick a class, slay monsters in the wilds and the endless dungeon, collect ever-better loot, grow a passive skill forest, and descend deeper to fight bosses every five floors.

Controls & Keybinds

Mouse

Default keys

All of these are rebindable in Settings → Controls. Keys 1–4 now cast the four keyed slots of your action bar. Binds use the physical key code, so the layout is AZERTY/QWERTZ-safe; older saves are migrated forward automatically.

Classes

Your class sets your starting attributes, your per-level growth, a damage multiplier, and the set of active skills that unlock as you level. All four classes share the same passive Skill Forest — each starts in its own sector.

All characters start at Level 1 with base HP 100 / MP 50 / DMG 10, 4 health potions, 2 mana potions, and 0 gold.

Free starting kit (level 1)

Every class owns Strike plus its level-1 ability for free. Every other active is unlocked by spending an ability point once you reach its class level — see Active Skills.

Stats & Attributes

The four attributes

How your sheet is computed

On every gear/level/forest change the engine recomputes derived stats roughly like this:

"base" values grow each level by your class's HP/MP/DMG growth. The melee/spell multipliers (see Combat) are applied at the moment of the hit, not baked into the Damage number shown on your sheet.

Leveling & XP

Combat & Damage

Dealing damage

A melee hit rolls player.dmg × meleeMult × skillMult + rand(-3,3). Spells use spellMult instead. The multipliers come from your class and passives:

Critical hits

Taking damage (mitigation)

Incoming damage runs a fixed gauntlet — a Dodge roll can avoid it outright, then Armor, flat Damage Reduction, elemental Resists, War Cry and a Mana Shield each chip away at what's left:

v49 Resists are applied as element-specific + All-Resist, hard-capped at 75% — the same cap covers both direct hits and damage-over-time (Bleed is physical and therefore unresisted).

Attack & movement speed

Leech, Life on Hit & Thorns

• Life Leech — heals you for a % of damage you deal.
• Mana Leech — restores mana for a % of damage you deal.
• Life on Hit v49 — restores a flat amount of Life every time you land a hit, regardless of the damage dealt (great for fast, many-hit skills).
• Thorns — reflects a flat amount back to melee attackers when they hit you.

Status Effects

On-hit effects from skills and affixes apply timed statuses. Damage-over-time (DoT) statuses deal a share of the triggering hit each second. The same status can stack up to 3 times; re-applying refreshes the duration.

Active Skills

v49 Actives now run off a 6-slot action bar and are unlocked by spending ability points — you earn 1 ability point per level (from level 2). Reach an ability's class level, spend a point, and it's yours; that same pool also buys nodes in each skill's rune tree. Strike and each class's level-1 ability are free.

Most skills rank up to 5. A skill's effective rank rises with its Empower rune node and with +to All Skills bonuses — both boost the damage and effect of the skill.

v47 Hovering a slot shows a live tooltip — current damage, mana cost, cooldown, on-hit effect and any allocated runes — computed from the same coefficient table the skill actually fires with, so the numbers never drift.

Unlock levels by class

All active skills

Cost = mana · CD = cooldown · "On-hit" = the status it inflicts.

The action bar & loadout v49

Six slots, assigned from the Abilities tab of the Skills panel (K):

Each slot shows its key, icon, mana cost, current rank (R#) and a sweeping cooldown wipe. The XP bar and level badge now live inside the action bar itself.

Rune trees v49

Every active except Strike has its own small rune tree (21 trees in all). You spend the same ability points here as on unlocks, and a tree is refundable in full at any time, for free. All trees share one shape, growing from an Empower root:

Node level-gates and the shape options depend on the skill's archetype (projectile, multi-projectile, chain, area or utility). The exclusive shape notables let a skill fork, pierce, explode on impact, chill, knock back, echo (cast a second time), linger, and more. Examples:

• Fireball (projectile): Volatile (explode on impact), Splinter (fork in two) or Impale (pierce everything) at Lv 3; keystone Seeker (homing, +15% dmg) at Lv 5.
• Chain Lightning (chain): Arc Splitter (+1 jump) at Lv 8; Wide Arc, Echo Strike (cast twice) or Overload (+25% dmg) at Lv 10; keystone Devastate (+40% dmg) at Lv 12.
• Whirlwind (area): Wide Reach, Echo Strike or Overpower (+25% dmg) at Lv 7; keystone Devastate (+40% dmg) at Lv 9.

Allocation mirrors the Forest: you must already own an adjacent node (every path roots at Empower), meet the node's level requirement, and only one node of an exclusive group can be taken. These rune level-gates are separate from the ability's class unlock level.

Skill Forest (Passives)

Press K to open the Skills panel and switch to the Passive Forest tab v49 (its sibling tab is Abilities). The Forest is a connected web of passive nodes: you start on your class's start node and spend 2 skill points per level (a pool separate from ability points), allocating any node adjacent to one you already own. Nodes come in four kinds:

Three sectors

The tree radiates into Strength, Dexterity and Intelligence wings. Each holds a notable and a sector keystone:

Outer keystones & cross-sector notables

Cross-sector notables: Warmonger (+10% Melee & Spell, +4 Crit), Trickster (+10 DEX/ENG, +3 Crit), Bulwark (+10 STR/VIT, +8 Armor).

Special Effects

These come from unique items, set bonuses, and Forest keystones. They stack from all sources.

Items & Rarity

Equipment slots (7)

⚔️ Weapon · 🪖 Helm · 🛡️ Armor · 🧤 Gloves · 🥾 Boots · 💍 Ring · 📿 Amulet. Weapons grant base Damage; armor pieces grant base Armor; rings and amulets have no base stat (their power is entirely in affixes & effects).

v49 Items can also roll sockets that hold gems — up to 3 on weapons & armor, 2 on helm / gloves / boots, 1 on rings & amulets. A gem's bonus depends on the slot it sits in (see Gems & Sockets).

Rarities

Higher rarity multiplies an item's base stat and every rolled affix, and grants more affixes.

Base stat & item level

An item's power scales with its item level (ilvl), which is set when it drops:

Affixes

Affixes are the random modifiers on magic/rare/set gear. Roll ranges grow with item level (il); higher rarity then multiplies the rolled value. The table shows the raw roll range before the rarity multiplier.

Unique Items

Uniques (✦) have hand-tuned affixes and a signature effect. Their base stat still scales a little with ilvl. There are 16:

Item Sets

Set pieces (green) grant escalating bonuses as you equip more of the same set. Each set has 4 pieces; collect them for the full payoff.

Upgrading, Enchanting & Gems

Town craftsmen work on your gear, gems & potions. The Smith and Alchemist are in every town; the Enchanter appears in the main towns; the Jeweler is exclusive to Emberhold. Crafting spends two currencies — Gold and v49 Dust ✦.

The Smith — Upgrade · Reforge · Salvage · Socket v49

The Smith now works across four tabs (its old potion upgrades moved to the Alchemist in v47):

Reforge Dust cost by rarity: Common 8 · Magic 12 · Rare 16. The Smith's old random single-affix re-roll was removed in v46 — chosen enchanting lives with the Enchanter below.

Gems & Sockets v49

Gems drop from monsters — especially Champions & Treasure Goblins — into a gem pouch, then slot into an item's sockets. A gem's bonus is slot-dependent: the same gem grants one stat in a weapon, another in armor, and another in jewelry.

"Armor" covers helm, chest, gloves & boots. Each gem has five quality tiers — Chipped → Flawed → (plain) → Flawless → Perfect — and the bonus grows with quality. Gem bonuses are flat (they aren't multiplied by an item's upgrade level).

• View every gem you hold — and its per-slot stats — in the inventory's Gems tab. Gems stack with no limit and never take up backpack space.
• Get sockets at the Smith (Socket tab), or roll them on a drop.
• Insert / remove gems at the Jeweler — removed gems return to your pouch.
• Combine three gems of one quality into one of the next tier (up to Perfect) at the Jeweler.

The Alchemist — potions v47

A new ⚗️ NPC in every town that permanently improves your potions (these upgrades used to sit on the Smith). Refilling potions is still free at the Cauldron.

The Enchanter — chosen imbue v46

Pick any item, then choose exactly which stat to imbue from a wide pool (Damage, Life, attributes, Crit, Crit Damage, leech, resists, the new skill/elemental/regen affixes, and more). The enchant is stored as a single extra modifier on the item (marked ✦); re-enchanting overwrites the previous one, so an item only ever carries one chosen enchant.

The chosen enchant is deliberately excluded from an item's sell/buy value, so re-imbuing doesn't inflate prices.

The Jeweler — accessories & gems v46

Emberhold-only. The Jeweler sells fresh rings & amulets and will re-roll all affixes at once on any ring or amulet you own (rolling fresh values for every existing affix). Same cost formula as an enchant:

v49 The Jeweler is also your gem bench: insert gems into sockets, remove them back to your pouch, and combine three same-quality gems into one of the next tier.

"itemScore" weighs base stat, each affix, special effects (+40) and set membership (+15), scaled by upgrade level — it's also what drives sell/buy prices.

Economy & Town Services

Gold & Dust

Gold drops from monsters (more from elites and bosses, and deeper floors). Spend it at the Merchant (buy & sell gear), the Smith (upgrade, reforge, sockets), the Alchemist (potion upgrades), the Enchanter / Jeweler, and the Gambler. v47 Vendors no longer sell potions — refill free at the Cauldron.

v49 Dust ✦ is the crafting currency, earned by salvaging gear at the Smith and from bulk-selling junk. It pays (alongside gold) for Reforging and adding sockets; per-rarity Dust values are listed under crafting.

The Merchant

The Merchant restocks 6 items near your level whenever you enter town.

Town services & where to find them v46

Each town hosts a different roster of NPCs. The starter town has the essentials; the unlockable Emberhold gathers the full set, including the Jeweler and a Premium Vendor.

The Gambler

Pay gold for a surprise item — you don't see it until it's bought. Item level and odds improve in higher-tier towns:

Loot Filter v46

Set in Settings → Loot. Toggle which rarities and slots you care about, and a minimum item level. Anything that fails the filter is auto-salvaged the instant you walk over it — converted to its sell value in gold v49 plus Dust ✦, never destroyed, never cluttering your bag.

• Unchecked rarity or slot → salvaged on pickup for gold + Dust.
• Item level below your minimum → salvaged… except Set and Unique items, which always bypass the minimum-level rule so you never lose them.
• Gold, potions and gems are always picked up regardless of the filter.

Potions

• Health potions also cleanse one DoT (Burn / Bleed / Poison).
• The town Cauldron fully heals your HP, restores your mana, and refills both potion types — for free.
• You carry up to potionCap of each (base 10, up to 30 via the Alchemist).
• Potions and gold are also dropped directly by monsters.

Zones & Travel

v49 The wilderness is three separate, portal-linked biome maps — no longer one open world. Each is its own bounded arena you enter through a portal; from inside a biome you can step to the next or previous biome, into its adjoining town, down the cave into the endless dungeon, or open the Waypoint (fast travel, G). A town joins your waypoint network once you've physically reached it at least once.

The wild biomes v49

Each biome is rebuilt fresh on entry (radius ~150) and paired with one town. They form a chain — Greenwilds → Frostfen → Ashlands — and a biome's level fixes the difficulty of the monsters spawned in it.

Towns & the dungeon

Finding towns & fast travel

• Stepping into a town portal travels there and discovers that town. Discovered towns then appear in the Waypoint network for instant fast travel; undiscovered ones show as "— undiscovered" until you find them.
• Entering a biome auto-discovers its adjoining town, so the chain of biomes naturally reveals the chain of towns.
• Depth selector v47: from the Waypoint you can jump to any dungeon depth you've already reached (1 … your deepest), not just Depth 1 or your deepest checkpoint.

Difficulty & Scaling

Difficulty tiers v50

Cycled on the HUD or in Settings. Tiers change mechanics, not just multipliers, and are earned: each unlocks once your hero reaches its required Descent depth (on the main menu, your deepest saved hero counts). Loading a hero that hasn't earned the current tier clamps it down.

Depth scaling (dungeon)

On top of difficulty, dungeon floors ramp with depth d (early floors near-linear, late floors curve up hard):

Wild scaling

v49 regionLevel is the level of the biome map you're in — 1 (Greenwilds), 7 (Frostfen) or 14 (Ashlands) — fixed on entry, so the deeper into the biome chain you travel, the harder its monsters hit.

Enemy resistances also deepen with depth (existing resistances grow stronger, floored so nothing becomes fully immune); vulnerabilities are left as-is.

Monsters

Eight base archetypes spawn in the wilds and dungeon (their stats are then scaled by difficulty and depth). Resistance <1× means it takes less of that damage; >1× means it takes more (a vulnerability).

The Shaman and the Wraith fire homing orbs from range and keep their distance. Brutes are big, slow, high-HP bruisers. Skeletons shrug off poison but crack to physical and fire; Imps and Hellhounds are fast infernal hunters that resist fire and hate frost.

Where they spawn v47

Each wild biome draws from its own monster pool. The dungeon rolls a random biome each time you enter, and that biome decides both the theme and the monster pool — e.g. Catacombs & Bone Cathedral field Skeletons, Frozen Wastes & The Void send Wraiths, and the Infernal Deep (and the Depth-666 Inferno) is packed with Imps and Hellhounds.

Elemental damage types

Damage is typed as Fire, Frost, Poison, Lightning, or Physical. ("Cold" is treated as Frost.) Match the element to a monster's vulnerability to do more; avoid hitting its resistance.

Elites & Champions

Sometimes a tougher version of a monster spawns, glowing with an aura. Elites are ×3 HP, ×1.6 Damage, ×4 XP and bigger, and carry one or more modifiers. A Champion pack is an elite plus three normal minions.

Named Champions v49

On a floor with a Champion bounty, a single named Champion stalks the level — an elite with a gold nameplate and a name like Gorehowl the Render or Ymira Frostfang. On top of its elite modifier it gains ×2 HP and ×1.25 Damage. Killing it is lavish: 5 items, a big gold purse, 2 potions, and a 50% chance of a gem.

Empowered monsters

From dungeon depth 6+, ordinary monsters have a growing chance (up to 50%) to spawn Empowered: ×1.6 HP, ×1.35 Damage, ×1.12 Speed, ×1.4 XP, and they erupt in a small blast on death.

Treasure Goblins v49

Rarely (≈3% of dungeon waves) a Treasure Goblin appears, wrapped in a golden glow. It's harmless and immediately flees — catch and kill it within ~18 seconds or it escapes and you get nothing. Crack it open for 3–4 items, a heap of gold, and a 60% chance of a gem.

Loot

• Elites always drop an item (best of several rolls) plus gold and often a potion.
• Normal monsters: ~85% gold, ~30% item (rising with depth), ~12% potion.

Dungeon Floor Events v49

Beyond the boss every fifth floor, ordinary dungeon floors now carry their own optional content: a floor bounty, a couple of shrines, and the occasional Treasure Goblin.

Floor Bounties

Every non-boss floor from Depth 2 rolls one bounty, shown on screen. It's a soft objective — the stairs down stay open whether or not you finish it — but completing it pays well.

Reward: 2 items (ilvl + 2), 60–120 gold (+ depth × 10), a potion, and about 15% of a level's XP.

Shrines

2–3 shrines spawn per floor; each is single-use — walk up and press E to commune. Roughly a quarter are Cursed; the rest split evenly among the three boons.

Treasure Goblins

The fleeing golden goblin can appear on any dungeon floor and escapes with the loot if you don't catch it in time — full details under Elites & Champions.

Bosses

A boss guards every 5th dungeon floor (depth 5, 10, 15, …). It blocks the way down until slain. Six named guardians rotate floor by floor, each with its own model, aura and a fixed combat variant; the deeper forms only join the rotation once you reach their depth:

v50 Every boss now runs a signature ability kit (breath cones, expanding ring-waves, add-phases at 50% HP, …) and big hits are telegraphed — a growing ground marker gives you a dodge window before the damage lands. Felling Pyraxis on Inferno grants the Sigil of the Inferno, unlocking a Waypoint straight to Depth 666.

Boss stats

Boss rewards

• 5 items, each the best of several rolls at ilvl + 4 and boosted quality.
• 150–300 gold (plus depth × 20).
• 2 health + 2 mana potions.
• The portal to the next floor opens.

Belphegor, Lord of the Inferno v47

A secret final boss waits at Depth 666 in The Inferno — a unique hell biome you can reach only by descending (the depth selector will not jump you there). Belphegor is roughly a normal boss with ×3 HP, ×1.5 Damage and ×4 XP on top of the usual depth & difficulty scaling, with a giant body and a punishing kit: twin fire + chilling volleys, ground slams, short teleports, a self-shield, and it summons broods of Imps & Hellhounds. Like every boss it enrages at 50% HP.

Saves

Export & Import v48

Open Settings → Saves to back up or move your characters — it works fully offline:

• Export writes all three slots plus your settings as a JSON blob. Use Download File to save a .json backup, or Copy to put it on the clipboard.
• Import takes that JSON back — paste it (or Load File) and hit Import & Reload. After a confirmation it replaces all local saves & settings and reloads the game (old/lower formats are migrated forward on load). Export first if you want to keep your current saves.

Handy for backing up before a risky build experiment, or carrying a character to another browser, profile, or PC.
