gem setups : -

ground slam - multistrike - conc effect - melee physical damage - faster attacks - inc AOe

Leap slam - faster attacks - endurance charge on melee stun - fortify - stun

vengence - curse on hit - asssins mark // EC

CWDT - immortal call - increased duration - molten shell

vaal haste - vaal ground slam - blood rage - increased duration

maybe :

herald of ash


Uniques : -

abysses if i had lightning coil

hegmonys era or just better rare staff with 8.5+ crit

belly of the beast or just a high armor life resists chest piece


because this is my first ever attempt at doing a build im very scared of what could happen but i have good knowledge to work around things and problems that may come with this build
