Minimum Forge: from this level on the effect comes from the gem chest, PvE drops and cutting. Above the active limit the strongest gems count; the rest stay socketed with no effect.

What it does

Raises the hero’s defense by a percentage — the title’s defense at its current level plus equipment. Stacks with the set bonus.

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
BattleThe hero takes less damage from the fight.
GvG duelEvery blow taken removes less HP.
ColossusReduces the Colossus’s blow, up to 35% mitigation.

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 III+6%+2.4%
Tier IV+11%+4.4%

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.
