Figured I'd put a guide just in case any one has issues. When doing The Path of the Warrior quest, you'll first be required to scale a mountain and obtain a cowl from a totem pole. Getting up is fairly easy. A few sirens and harpies that shouldn't prove a problem. Jumping and grappling can be a little tricky but again, fairly easy. Once you obtain the cowl, you'll notice a short path that wraps around and abruptly ends, with the mountain dropping sharply down. Simply walk towards the edge of the path and you'll automatically start sliding directly towards the 2nd part of the quest, which requires you to go into an underwater cave. I guided myself a little bit towards the entrance and about 3-5 seconds after completing sliding, cheevo popped.
