Grind

Grinding a weapon gives it an additional +2 ATP. All weapons have limits on how much they can be ground, and some weapons cannot be ground at all. A weapon's grind is shown next to its name with + sign in front of it.

Monogrinders, digrinders and trigrinders are items that are used to add grind to weapons. They will add +1, +2 and +3 grind, respectively.
