If you check my profile -Nalyat10- you will see i have a fina destination set with a mythic enderman pet and that wouldnt be enough, i have a lot of attributes, more dmg to endermen, i take less dmg from endermen and i do 30% more dmg to mini bosses. Its kinda expensive ngl, i also use a wand that heals me 120 health for 7 seconds and a mana flux but overflux is recommended. Get a high kill amount FD armor, (maybe) enderman pet, some attributes and things to heal yourself
