Use this as a base for your own build. Yes its still very powerful but not as OP as used to be. One thing id say, use druidic set and druidic bonus to save slots and use many of the modern sets depending on the build.
Anything is good with poison. Plagued, druidic, regen, cosmic power, a projectile with timewarp, demonic, crushing blow, blight, 300% or so ED, use Energy/fury/alchemy instead or bloodmagic, Momentum with move speed, add dodge and or block for survival, remove HP and MP (which was needed for equivalence max regen before nerfs combined with other regens), crystal crit and crit chance, rage set, natures such as strength, Pathfinder, Angelic, coat, etc. So many ways to adopt this build in any class with the core concepts and btw skullshield is still OP and wand too with high enough barrage hero points, Multi Attack, extra attack, etc.
This was my favourite OP build and i remember it was Cronos favourite too. This is what inspired me to get good.
