Now that we're out of combat, we can all take a short rest. You can spend hit dice to regain hit points that way Snake.<br/><br/>The way that works is, when you take a short rest you can roll any number of your hit dice, roll them, and gain that many hit points back, plus your constitution modifier per die. So as a Level 2 fighter, you can roll up to two ten-sided dice , adding your con bonus to each die you roll, and there you go, hit points!
