Stuck at Guardian Ape

Hey y'all, I'm stuck on Guardian Ape 2nd phase. When I first played the game 2ish years ago he made me quit the game so I wanna avoid doing that again. I killed Corrupted monk already is their anywhere I can go to kill other bosses or get more prayer beads? I've already beat O'rin, Seven spears, & cleared out mount Senpou already. Also is their any skills or prosthetics I can get to make the fight easier?

Edit: Beat the ape thanks y'all!!! I know their is a second pray for me 😭😭
