So i noticed when farming sinias and mezzaluna for prod that if i use kill stick and allow hp to drop a certain amount we can avoid transforms/booms. Im curious if this is a bug or if its the intended purpose. It does make farming materials simple xD
It's different with every boss. Some of them use an hp trigger, some get harder if you kill them too fast, others if you don't kill them fast enough. It's hard to say really.
I think most classes can avoid the boom if they learn the triggers. Just alchemist have a larger variety of spells we can use. We are not stuck using the one hit wonder nor are we super worried about keeping up with buffs for sustained dmg/def. We run though our list of spells and see what works and what doesn't.
I know for me, if I can't kill it with a 200k blizzard or a 400k poison bomb, I gear up for anything the boss could throw at me until I memorized their pattern. Then Ill just take what I need to kill quickly without wasting to much spina on spells.
Based in my experience, best way to avoid boom (with stun+hp delete at same time or one of them lol) is via Stone skin or any smiliar stuff (shield of light, mins song (forgot which one), and solid skin). Basically, ench, gladi, mins, and serv are suitable class for this stuff.
