Crit, Block and the flat "value" stats

Several stats come in two forms: a percentage and a flat "K" value. They are not interchangeable. The flat version is divided by a hidden per-rank number, and loses most of its worth as you climb.

The crit roll

crit chance = 5%
            + ( your Crit Rate %  + your flat Crit Rate / your base crit value )
            - ( their Crit RES %  + their flat Crit RES / their base Crit RES value )

Everyone has a hidden 5% base crit. Your percentage stat adds directly. Your flat value is divided by a per-rank base first, the same way Elemental Mastery is scored.

Crit damage is max(1.3, 1 + Crit DMG % − their Crit RES %), so a crit always deals at least ×1.3. Crit and Block are mutually exclusive: a blocked hit cannot crit.

What "+1K Crit" is really worth

Percentage points are not damage

Crit rate only pays out through crit damage. Expected damage is 1 + crit chance × (crit multiplier − 1), so with a 1.59× multiplier, +11% crit rate is about +6% damage. That is real, but far less than the headline suggests.

The two stats gate each other. Crit Rate is the better buy while Crit DMG % > 5% + Crit Rate %. Past that point Crit DMG takes over. They are balanced when the two numbers are roughly equal, and crit rate becomes worthless entirely once effective crit chance reaches 100%.

The same pattern elsewhere

Each stat below is scored the same way, flat value divided by a hidden base that grows each rank:

• Effect Hit Rate and Effect RES, each with its own hidden base.
• Block.
• Accuracy. It counters enemy Block. It does not change your chance to hit.

At level 83 the Effect base is 6,049, so an Effect Hit Rate of 2.73K is contributing about 45% effect chance.
