Combination tank/caster build for [Lavos] that adds an extra corrosive proc to his 1.
Second arcane can be whatever you need, A. [Continuity] can be downranked (4) to save a forma, I haven't noticed any practical benefits to status duration over 100% due to enemies dying too fast.
Can tank Steel Path, though usage of 1 for healing or a Vupaphyla with [Martyr Symbiosis] may be needed.

Use abilities like normal, 1 & 2 for status, 4 to nuke & 3 to reset cooldowns.
With sufficiently clustered enemies, gas damage Catalyze can prove a reliable method of killing acolytes.
