Which one should I get

star rage maximum is really only good if you have a move that makes you invincible (like hollow purple), idk about heian awakening

imo wait till you get jacobs ladder or six eyes cuz blackhole is only good if you have hollow purple

I would say to test them out I the sandbox if you can and watch some videos on what you like best and pick from there

I will also say though that I agree with waiting for Jacobs ladder, it is actually okay on its own for bosses it does about 4-6k damage depending on your technique level I believe and it just gets better when you get multiple in the AOE I think it's the best technique in the game despite what people say about bosses and such. Ik all this because I use it myself and its one of the best decisions I've ever made in the game

heian awakening kinda ass. total collapse is good but unless you can get away fast enough (usually need a agility vial) or have an iframe move like hollow purple then you'll also get like 4-6k damage taken
