Hi how do you beat the Leechgrave cause i can never beat that damn thing!

to beat it, you need to defeat the tentaclaws first. i would suggest using a good high damage weapon and a critical ring and some hi-potions.
once tentaclaws are down, go in and PWN the leechgrave.

what the other guy sinabi and when need health RUN!!!!!! and heal your self

Attack it's Tentaclaws and hit the coffin-shaped weak spot and RUN!!!!!!!!

I defeated it easily without fighting off the tentaclaws. IDK how, maybe good luck and good weaponry? :I
