So yeah, what is the Lip's Stick from melee supposed to do?
If someone gets hit with it, a small flower grows on their head. With time, the flower gets smaller and smaller. As the flower's shrinking, it does some damage to the person who got it. If you hit someone, say, 3 times in a row, the flower gets bigger and thus does more damage for longer than one hit with it. It's a pretty useful item, actually, although it's pretty underplayed.
The Halberd is cool, also. The arm cannon and laser is interesting, but from the pictures i'm not exactly sure how it'll work.
