I just beatThe Guardian Ape on my first attempt! I saw him just chilling in the water just below the shrine, so I figured I'd at least give it a shot, but I didn't expect to actually beat him. It's definitely a fight that Soulsborne fans will have an easier time with. I personally thought his second phase was easier than the first. His moves were much more predictable.
Same. He can pretty much be posture broken the second phase, while the first is a typical and brutal Souls beast fight that comes down to whittling his health down.
