The Official Monster Hunter 3 Ultimate Topic

Deviljho is pretty scary when you first see him, but he's actually really easy as a blademaster. Just stick by his legs. You take more damage running around like a headless chicken trying to avoid his attacks then if you just stick close/under him. Most of his attacks involve him twisting and lunging forward, while he only has one or two very telltale attacks that can hit you when you're at his legs.

IUNNO MAN...I'd be fine with that if I actually had armor on (I generally stick close to him anyway), but I just kept getting 2-shotted(?). I just need to continue learning how to time my attacks better.
