Stamina Points

You've honed your body and mind to push past your normal limits, allowing you to perform extraordinary feats in the heat of battle. You gain the following benefits:

1. You have a number of stamina points equal to half your largest hit die + your Constitution modifier (minimum of 1). You regain all expended stamina points after completing a long rest.

2. As an action, bonus action, or movement, you can spend one stamina point to gain an additional action, bonus action, or movement. This extra action can be used to perform any action that you would normally be able to take, including casting spells or making attacks.

3. If you have no stamina points remaining, you can choose to expend one level of exhaustion to gain a stamina point. Doing so immediately imposes the effects of the corresponding level of exhaustion on you.
