Equipment Basics

Four gear slots with flat stats, rarity-driven bonus modifiers, item levels and artifact sockets.

While materials drop from all enemies, equipment drops only from bosses. Each item has a slot stat, a rarity and an item level. Uncommon drops have a 5% chance of 1 artifact socket; newly merged Rare and higher items always have at least 1.

The four slots

Helmet - flat HP
Armor - Damage Reduction
Weapon - flat damage
Boots - flat dodge

Rarity ladder

Rarity	Modifiers	Sockets
Common	0	0
Uncommon	1	0: 95% · 1: 5%
Rare	2	0: 0% · 1: 100%
Epic	3	0: 0% · 1: 80% · 2: 20%
Legendary	4	0: 0% · 1: 85% · 2: 15%
Mythic	5	0: 0% · 1: 60% · 2: 35% · 3: 5%

Uncommon drops have a 5% chance of 1 socket; Common drops have none. The higher-tier ranges in the table describe the paid socket reroll. A merge into Rare or higher rolls the new rarity's socket count and keeps the better of that and the base item's, so a merged Rare has 1 socket, an Epic 1 or 2, a Legendary 1 or 2 and a forged Mythic 1 to 3; a merge never loses a socket. The artifacts stay in the sockets the base keeps, and the sacrifice returns its own to your inventory. Merging two Mythics keeps the base item's sockets as they are. Items you already own keep the sockets they have. The item sheet offers the paid reroll on Epic, Legendary and Mythic items, and on older Rare items with no sockets; a reroll never lowers the count. Uncommon items cannot use the paid reroll.

The wave part of the curve saturates — it approaches a fixed span and never crosses it — while each world adds a flat step. Deep-farming one world hits a ceiling no number of waves clears; moving up a world is worth more than thousands of further waves.

Boss-dropped equipment is only ever Common or Uncommon (a boss appears every 10 waves). Higher rarity gear (Rare to Legendary) is made, not found: Merge two items of the same slot and rarity — and craft Mythic in the Forge.

Inventory limit

Equipment holds 300 items. A pack of 50 more slots costs diamonds (50 times the pack number, so every pack costs more than the last) and is permanent. At the cap a boss drop is NOT collected - it is lost, not queued, and an "Equipment full" warning shows instead. The counter in the Equipment screen shows the cap and the menu shows a red dot. Salvage or merge to make room; nothing you already own is ever removed to fit a new drop.

Upgrading an item

An item can be upgraded twice with diamonds. Tier I costs 50 and multiplies EVERY stat on the item by 1.05; Tier II costs a further 200 and takes the total to 1.10. The multiplier applies to the whole stat block, not just the slot bonus.

Two things are worth knowing before you spend. MERGING DOES NOT CARRY THE UPGRADE — the merged item is a new item at upgrade level 0, so a Tier II you merge away costs you the full 250 diamonds. And salvaging refunds essence only; upgrade diamonds are never returned. Upgrade the piece you intend to KEEP. Merging two Mythics is the exception: the base keeps its upgrades.

Item power

Item level scales the base stat, and magical-power modifiers add build effects on top. Epic powers roll from one shared pool, but LEGENDARY powers are slot-specific — each item type (helmet, armor, boots, weapon) has its own set of three, and a power from another slot can never appear on the item. Higher worlds raise item level, so pushing worlds is the fastest gear upgrade.

Stat pool

Every item rolls stat modifiers from four categories. How many depends on rarity — Uncommon 1, Rare 2, Epic 3, Legendary 4, Mythic 5. Rerolling in the Forge swaps each modifier for another stat in the SAME category. Each piece also carries a fixed slot bonus (Max HP on helmets, Damage on weapons, and so on) that is always present and never rerolled.

Category	Stat	Type	From
ATK	Bullet Damage	Flat	Uncommon
ATK	Armor Penetration	%	Uncommon
ATK	Bleed Chance	%	Uncommon
ATK	Bullet Dmg %	%	Epic
ATK	Melee Dmg %	%	Epic
DEF	Damage Reduction	%	Uncommon
DEF	Max HP	Flat	Uncommon
DEF	Shield HP	Flat	Uncommon
DEF	Max HP %	%	Epic
DEF	Shield %	%	Epic
RES	Drain Resist	%	Uncommon
RES	Poison Resist	%	Uncommon
RES	Stun Resist	%	Uncommon
TEMPO	Attack Evasion Chance	%	Uncommon
TEMPO	Counter Chance	%	Uncommon
TEMPO	Poison Duration	%	Uncommon
TEMPO	Stun Duration	%	Uncommon
TEMPO	Regeneration %	%	Epic

Percentage variants unlock at Epic. Flat values (Max HP, Damage, Shield) scale with item level; percentage modifiers do not.
