I kinda cheated using "all buffs" from lui afk but all the gear is post Yharon...I think lol, I show the gear at the end but next time I should organize it.

I not a no hit god so this is good for me.

Btw to change the boss health percentage its in the Calamity config I didn't show but if you play on a world that's on master mode and death and the health percentage is set to 200 the health should be the same if you don't have any other mods effecting bosses.
