Supreme Ego Smite (HCSSF)

https://pastebin.com/1SAmG6Ls

Concepts

• Smite + Wrath scaling efficiently through Supreme Ego and Aura Clusters
• RT + Supercharge for Can't Miss and free Lucky Damage, exploiting the huge lightning roll range
• Frostbreath for Double Damage
• Tribal Fury (Ancestral Call overlap trick) for doubled damage again
• Berserker Rage scaling for free damage
• Perma Berserk
• Near 100% Ancestral Cry upkeep for insane clear
• Glancing with max block (+ eventual life on block shield)
• Vaal Molten Shell possible with a bit more Armour investment.
• 200%+ Life
• Blood Magic

Notes

• Aspect of Carnage is not recommended in HC but go nuts in SC.
• Crit is possible with Precise Commander scaling instead?
• Blitz is possible if you go crit.
• Multistrike + some adjustments is huge damage but loses exert?
• Vaal Haste becomes a second Berserk but means VMS downtime.
• Melee Splash works with Smite and could double clear if there's a good way to get it.
• Ascendant, Guardian, Necro and many other viable classes with tradeoffs are possible!

Alternative Build

• Another option is going completely with another skill and just using Smite for the buff.
• Could allow for very crazy scaling with the right setups (dropping Strike investment).
