Equipment Classes

Equipment classes

Every weapon, tool and armor piece receives a random class when it is crafted, whether at a Matriochka station or a vanilla crafting table. The Class Table raises the class level, and a Chance Doll rerolls the class. Bonuses are written into the item's attribute modifiers on the server and shown in its tooltip.

The six classes

Class	Can appear on	Design intent	What the code gives (at level L, multiplier m = 1 + bonus)
Guardian	Armor	Armor, knockback resistance	Armor + max(1, 15% of the piece's armor) x m; knockback resistance + 0.04 x m; one extra armor layer, half as sturdy again (see Nesting systems)
Berserker	Weapons, armor	Damage, attack speed	Weapon: attack damage + 8% of its damage plus the whole bonus of its level (+8% at level 1, +18% at 2, +28% at 3, +43% at 4, +58% at 5; at least 1 damage), attack speed + 0.08 x m. Armor: +3% x m attack damage
Prowler	Weapons, armor	Movement speed, dodge	+3% x m movement speed, and a chance to dodge a blow: 2.5% per piece, more with the level, at most 30%. A dodge shows a puff of air and "Dodged"
Reaper	Weapons, armor	Life steal, soul gain	Luck + 0.5 x m, and life steal: each Reaper item heals you for 3% x m of the damage you deal. Killing a creature also heals a share of its health. Extra souls: 5% per piece (more with the level) of every kill's souls, and even creatures worth no soul may yield one
Survivor	Weapons, armor	World effect resistance, recovery	Max health + 1 x m, and each Survivor item reduces gauge changes (toxin, heat, noise) by 6% x m, capped at 60% in total
Prospector	Tools	Mining speed, ore luck	Mining efficiency + 3 x m, luck + 0.5 x m

Pools: armor rolls among Guardian, Berserker, Prowler, Reaper and Survivor; weapons among Berserker, Prowler, Reaper and Survivor; tools are always Prospector. An item counts as a weapon if it has the weapon component or is a sword or axe, and as a tool if it has the tool component (pickaxes, shovels, hoes, the Drill).

Levels

Level	Bonus	Upgrade cost (souls)	Shell Shards	Allowed once
1	+0%	-	-	Start
2	+10%	10	1	World 2 boss defeated
3	+20%	30	1	World 4 boss defeated
4	+35%	90	2	World 6 boss defeated
5	+50%	270	2	World 8 boss defeated

Going from level 1 to level 5 costs 400 souls in total (10 + 30 + 90 + 270). The level cap follows your group's highest defeated boss: level 2 after World 2, 3 after World 4, 4 after World 6, 5 after World 8. Creative players ignore the cap. Every upgrade also costs Shell Shards, the boss material: 6 from level 1 to level 5. Every boss leaves 3 Shell Shards to each player who fought it, and a mutated boss 2 more: enough to bring each world's weapon to the class cap (see Balance).

Berserker weapons since 0.4.0

A Berserker weapon used to add 8% x m of its damage, so 8% to 12%, far from the design's +50% at level 5; the reference creature took 6.7 hits in World 10 instead of 5. It now adds 8% plus the whole level bonus, and the reference creature again takes about 5 hits in World 10. The bosses' Shell Shards went from 2 to 3 in the same pass. The figures are in the Balance report.

Talents

On top of its class, each class has a tree of twelve talents, learnt at the Class Table with souls and Shell Shards. A class's talents act only while you wear or hold at least one item of that class. See Talents.

Rerolling

The Reroll button of the Class Table consumes one Chance Doll and souls, and draws a new class that is always different from the current one. The level is kept. The soul cost doubles with each change on the same item:

Change	Souls
1st	20
2nd	40
3rd	80
4th	160
nth	20 x 2^(n-1)

The Chance Doll is crafted at the Matrix Workbench (2 Oak Planks, 1 Red Dye, 2 Gold Ingots) or bought from the Doll Peddler for 6 Emeralds.

Tools only have one class, so they cannot be rerolled: the table refuses and takes nothing.

Inverting

The Inverter of World 6 swaps the class, class level and enchantments of two pieces of the same kind (two armor pieces, two weapons or two tools). Each loses a quarter of its durability and counts one more class change, and an enchantment the other piece cannot carry is lost.

Armor layers

Armor pieces can carry Lacquer Layers laid at the Class Table. A piece holds 1 layer, plus one at class level 3, one at level 5 and one for Guardian gear. See Nesting systems.

The newest world's gear

The gear of your group's newest world can only be crafted by players who took part in its last boss fight. See Multiplayer and groups.

Stored data

Each item stores its class, level and number of changes in a matriochka:gear component, which survives repairs and trades. Levels read from the component are bounded, so an edited item cannot go past level 5. Gear from other mods or vanilla shows its class and layers in its tooltip too.
