DoT debuff UC.
https://www.ranaldsgift.com/ this site doesn’t work on Mobile well, that’s why I don’t have a link to the UC build right now ;-;
But take Outburst, Enfeebling Flames, and the Flame aura ult. Most of the time I see this build ran with dagger because heavy 1 has lots of stagger and sets things on fire, use push or push attack after heavy to apply more DoT in a wide arc to enemies, rinse and repeat. Also dagger has a high headshot damage when it’s time to dish out regular attacks.
Beam staff works well with it, shotgun blast to build heat/debuff enemies. Any staff besides Bolt could work, but I think Beam is more versatile.
At high heat you have high melee so throw in as many melee attacks between DoT/debuff attacks as you want. It lacks in armor damage, boss damage, and CC, but still more fun and less cheesy than Bomb Balm builds.
Only time you need to vent is to mitigate gas/flamer/gunner damage or if you just really want to range attack some more.
Flame Aura Ult does a decent amount of damage with strength pot + debuff makes it strong versus Chaos Patrols in helping everyone else stay alive.
