Blood boil and cleave. Fire is coolest looking by far and slightly worse than the physical builds. Magic aka abyss is last place.

This is not true lol

BB could be second, a fairly distant second.

wrong, if you think bb is worse the that’s just a skill issue on your part

100% agree lol

Es is faster, safer and better at most or all things AND requires no skill! Therefore it is best build.

Cleave is interesting, I like that it’s a physical build and having more of those is nice.

Blood boil is strong. But it needs good items, and its not the best boss killer. I had to nearly kill my demon to beat tz baal, and that with decent items and skillers.
Coming from an ES build, BB is stressfull. You have to take a look at your demons Life every second, because it depletes really fast when attacking. I also missed my insight and also having to worry about my mana. Syphon is great at fixing it BUT only works when you kill something. If your defilers are the ones killing something you don't get that life mana back.
So i went back to ES.
