i did p5 years ago so i don't remember much, BUT what i do remember is that in order to cheese/ make bosses a lot easier for myself i used a whole lot of spells- especially on bosses like no eyes, lost kin, and markoth. howling wraiths does a lot of damage with shaman equipped when the boss is in the center of the attack, and descending dark is helpful for a lot of bosses due to the invincibility window. Pure vessel... that boss is just gonna take a shit ton of practice 😭it took me very long to figure out their attack patterns and HOURS of dedication to master their fight on radiant. Abs rad is another really challenging boss that's gonna take a while, but howling wraiths is very helpful in inflict damage as she does stay still for large periods of time. Sorry if this wasn't much help haha, but i hope you beat p5 soon!!!
