Action Points
From NsdWiki
Action Points (AP) represent the number of activities you can perform in combat. Every action you perform costs a specified number of Action Points, from swinging a sword, to launching a spell, to grabbing a monkey out of your pocket. Characters start off with 6 AP, but more can be acquired through the Nimble Combatant trump. On your turn, you may perform actions until you run out of Action Points. When a new round starts, your Action Points are replenished.
