I’ve played only this character in scourge league, the play time is almost 6 days and in this time I’ve managed to complete 36 challenges, including aspirational content such as multiple wave 30 simulacrums, ravaged blighted maps, flawless breachstones and unrelenting emblems, even though I can’t recommend this build for the last 2. After min-maxing it during the league, i managed to get:

• 5K life pool/10k guard molten shell
• 87% maximum elemental resistances to mitigate elemental damage
• Over 40k armour and 3 endurance charges to mitigate physical damage
• As much chaos resist as the gear allows to resist chaos damage
• Elemental ailment immunity, up to 95% reduced effect of curses (would need t1 roll on flask)
• Fortify to lower all hit damage (this is buffed in 3.17)
• Berserk to lower all damage taken by 26%, give movement and attack speed and more attack damage
• Life gain on hit through vitality watcher’s eye for great sustain against packs
• Take no extra damage from critical strikes with brass dome
• Solid damage for a non crit attack build, however, won’t be a clearspeed monster and need a lot of buttons to press to maximize damage and survivability.
