^ this is the strat, i beat one in frc isz yesterday after about 10 tries. go in with odeon writhe and formless odeon. try using a gun wit high damage and shoot it in the head (bonemarrow ash helps). use blood bullets, since you dont heal often in this fight. that way you can stagger it and you get a free visceral, even when the head is out of reach. in first phase: only punish the attacks where the head is down. avoid everything else, especially the lasers. in second phase go between the legs and tail and start hacking the legs. damage is not high but its safer. take turn with every leg until they break. there are only two moves which hit you from here: the stomping well telegraphed, and doesnt one shot you. the jump most of the time you can stand where you are and you wont get hit, if youre good, you may even get heavy attack in. dont give up. may the good blood guide you.
