Lifesteal :v duhhh OP rogue can kill u easily in pvp

It's most effective on toons that do dot and aoe Dmg... Mages fireball/curse/ice/wind/clock are dot/aoe skills also useful for rogues using nox, and tanks with windmill. But it's mainly a Mage gem tbh.

1.5% lifesteak for normal skull

2.5% for grand skull.

Above posts answered everything about it.

Is that per gem?
