I am perfectly fine with the setup for Boolossus 1-cycle where you hit almost all the boos with the first ice ball. Once I do that, I ice and suck up the remaining boos. However, for whatever reason, the last boo always gives me trouble. I've heard that when the boo cackles, you should back up and switch to ice, but everytime I do this, the boo charges straight into me and damages me. What am I doing wrong on it?
dont go by a audio cue. have your vacuum out and face away from it. then when the last boo stops moving, switch to ice an back up. you can always check videos and ask for help from streamers if you need to. everyone is super nice
This is all a matter of feel. You just need to watch runs and see what other people do, and eventually you'll get the timing down. Also, if you're looking for a more definite explanation, then try moving a bit to the side and using the c stick to aim at the boo when backing up instead of just going straight backwards.
