During battles, you have a concise list of actions at your disposal: Attack, Defend, Swap, and Reserve. Attack and Defend allows your dinosaur to hit your opponent and block oncoming attacks. Swap allows you to switch your current dinosaur in the arena with another on your team at the beginning of every turn. Reserve is a special command that conserves your actions for later use. All of these actions require Action Points to be allocated to them before they can be used.
