CoSMOS Gamehacking Tool

The first boss (cigarra) in forest area 2 bugs out when it jumps and vanishes from my screen. Please provide something that allows me to just one-shot kill it.

edit: you can still provide it you want. I figured out the cosmos thing to change the boss hp to 1 so i could just one shot it and move on.
