Elden Ring Never give up

30th or so run-through of 'Fringefolk Hero's Grave' boss ceature 'Ulcerated Tree Spirit.'
Blind. No strategy guide, no consumables only with what I brought.
Ist death is pretty much what happened every other time. Insta-death or I get to 50% or so before the mouth grab and immolation.
Noticed that going for the big red patch behind the stepped-on-my-skull leg caused a stunlock to occur every now and then.
Noticed that my summons get nuked pretty quick so tried the Jellyfish because it flies and avoids the tailwhip.
Capped with the PSN included software. Got the PS5 direct from Playstation via the PS+ direct link (not the scalper price.)
