What it does

Chance for the hero’s blow to crit. Stacks with crit chance from equipment.

Where it works

Battle is every march with a hero (PvE, PvP and oases), resolved at once by the strength of both sides. Duels are blow by blow.

ModeEffect
BattleTurns into average damage: adds to the hero’s attack in proportion to the crit (2× plus Crit Damage). Against another hero, their Dodge cuts this chance by the same proportion.
GvG duelChance to crit on every blow (2× the damage, plus Crit Damage).
ColossusChance to crit on every blow (2× the damage, plus Crit Damage).

Value per tier

Value of each attribute on the gem. On a 2-attribute gem each one is worth less than alone; it appears from Tier III (from the gem chest, with the Forge at level 6) and only fits a Prismatic socket.

Tier II+1.5%—
Tier III+3%+1.2%
Tier IV+5.5%+2.2%
Tier V+9.5%+3.8%
Tier VI+16%+6.4%

Caps

The gem cap applies to the sum of the hero’s active gems; past the start of diminishing returns, each point is worth less. The same attribute from equipment comes on top of that cap and only stops at the battle cap.
