What? Let’s see:
- large AoE
- Lower Resist, which breaks immunities
- Corpse Explosion (fire/physical) for poison immunes or for clearing large groups (such as cows)
- tank (one point wonder Clay Golem)
- Decrepify if it’s too hot
- possibly UT viable (with revived Blunderbores)
Useless builds:
- fire trap sin (Inferno was/is bugged)
- throw barb
- fire druid (actually mediocre, but still inferior to wind druid; mainly due to low non-fire dmg againt immunes)
- poison javazon (lightning skills have too many synergies for a hybrid build)
- spearzon (Fend bug)
- summon druid (only one summon of each type at a time, which are too weak)
- warcry barb
