Rarity

Common through Legendary, with four tiers of random attributes.

Any piece of equipment dropped by a monster can come with extra attributes. When it does, the item gets a coloured name and a list of bonuses — and becomes a different piece entirely, while still being the same item.

The five tiers of rarity

Rarity decides how many bonuses an item carries. That is all it decides — how strong each bonus is comes from somewhere else, explained below.

Rarity Bonuses What it means
CommonThe plain item, nothing added. The overwhelming majority.
Uncommon1One bonus. Already worth keeping.
Rare2Two bonuses on the same piece.
Epic3Three bonuses. This is what moves high prices on the Market.
Legendary4Four bonuses. Gone fast whenever one is listed.

Tier: why the base item matters

This is the part that changes how you hunt. Bonus strength is not rolled — it comes from how good the item already was. Every piece has a tier from 1 to 4, set by its own armor, defense or attack value.

Boots with 1 armor are tier 1. Boots with 4 are tier 4. Both can roll Epic — and the tier 4 pair rolls far bigger numbers. In exchange, it rolls far more rarely: the better the base, the harder it is to come out enchanted.

That trade is what gives gear its value. A weak item with bonuses is common and gets you started; a tier 4 Legendary is the real prize, because it needs both strokes of luck at once — the good piece and the rare roll.

Quivers and two-handed bows/crossbows are the exception: they always use tier 1 odds, no matter how strong they are — which means the most generous band. That is deliberate: those pieces do not scale in tier, and locking them into the hard band would leave them with virtually no rarity at all.

The real odds

Below is the actual probability of each rarity, by tier. These are the server's numbers, not an estimate.

Tier Uncommon Rare Epic Legendary Anything at all
16.67%5.00%3.33%1.67%16.7%
23.64%2.73%1.82%0.91%9.1%
32.50%1.88%1.25%0.63%6.3%
41.29%0.97%0.65%0.32%3.2%

Read the last column: at tier 1, one item in six comes with a bonus. At tier 4 it is one in 31. And the number that matters sits in the corner: a Legendary at tier 4 turns up in one piece out of 310 — and it is the best item in the game.

Which bonuses can roll

Twenty of them, plus the elemental resistances. The number printed on the item is the tier: a tier 4 item shows +4 where a tier 1 would show +1.

Bonus What it does
Attack, Armor, DefenseAdd straight to the piece's value, recalculated every time you equip it.
SkillRaises the weapon skill. Only rolls on club, axe, sword, distance, quiver and shield.
MagicRaises magic level. Works for every vocation.
Max Health, Max ManaRaise your total health and mana.
Health Regen, Mana RegenThe tier is the amount healed per tick. Four tier 4 pieces add up to +16 per tick.
Movement SpeedYou walk faster.
Attack SpeedYou swing faster: −50 ms per tier, down to a floor.
Critical, Crushing BlowChance of extra damage.
Parry, BleedingDeflect hits and cause bleeding.
ResistancesReduce elemental damage — fire, ice, energy, earth and death.
Berserk, PerseveranceOnly work on Knight and Elite Knight.
Sharpshooter, Fast HandOnly work on Paladin and Royal Paladin.
There is no level requirement. A Legendary item works in full at level 8, with the same bonus it would give at 500. Find one early and it pays off from the first minute.

Details that save you frustration

  • Stackable items never roll. Potions, ammunition and food always come out common.
  • Wands and rods do not receive bonuses yet — the system knows about them, but their attribute list is empty.
  • The roll happens once, the moment the monster drops the item. There is no reroll.
  • Bonuses stack across pieces: four items with Mana Regen add all four values together.
  • Rarity travels with the item — it survives a trip through the Market and any trade.
