Hardest Brutal Boss so far?

[Akulvo]

I made it up to Blackbrew so far, havent fought the curse weaver yet but I've beat all the bosses below.

So far, the hardest has been Ziva or Tristan.
Tristan was rough to get used to with his quick scoping crossbow but I got the feel fro the fight now.
Ziva on the otherhand, STUPIDLY easy until she pulls out her green lightning gun. I didn't understand that its best to just treat it like a dodge phase and tried to fight it like her otherphases, only to end up getting blown up by the green orbs. I still dont quite have the feel to dodge the orb explosions properly, I kinda wish that there was some indicator for when the orbs were gonna blow up but w/e. I might just be missing a mechanic or something.
Aside from her green gun, she's incredibly easy.

What are your thoughts so far?

My thoughts so far is Brutal Tristan can suck the air outah' my butthole.
