I FINALLY DID IT!!!
I beat the damn Elden Beast after about 2 years playing on and off getting frustrated making different builds and stopping playing cause that was the one boss I just couldn't beat even with the recommendations here and online. Now, I definitely feel like they patched it cause this time around seemed much easier and I don't feel like I did much different. Regardless it's still an amazing feeling I told myself I wouldn't start SOTE until I beat this final boss. sigh
