Guard

Guard weapons allow you to fight defensively, using the weapon's long haft or flat surface for parrying. While you wield a guard weapon, whenever a hostile creature moves within your reach when you didn't move on your last turn, you can use your reaction to make a weapon attack with the guard weapon against that creature. If the attack hits, then it deals no damage, but the target immediately stops moving, and it speed becomes 0 until the end of its turn.
