Monster Hunter Tri has a skill system that takes time and practice to fully take advantage of. It can be a pain in the butt to go in and start manually trying to figure out what skills are useful, and how to get the ones you want on your armor set. Team Septicore has come to the rescue! They’ve created a tool that allows you to put together your dream armor set and edit on the fly. All without having to do any trial and error in the game. Better still, there’s saved armor sets from other users, so you don’t have to build your own even. Just pick the skills you want, and see how they made it.

These are screens for a nice set for a hammer user.
