D&D 5e Hit Points Explained

Hit points (HP) measure how much damage your Dungeons and Dragons character can take before falling unconscious. Maximum HP comes from your class hit die, character level, Constitution modifier, and optional bonuses from feats or race.

Level 1 Hit Points

At level 1, you take the maximum value of your class hit die and add your Constitution modifier. A fighter with a d10 hit die and +2 CON starts with 12 HP. A wizard with a d6 and +1 CON starts with 7 HP.

Hit Points at Higher Levels

From level 2 onward, each level adds one hit die roll plus your Constitution modifier. Many tables use the fixed average: floor(hit die / 2) + 1 + CON modifier per level. A d10 class averages 6 + CON each level after the first.

Hit Dice Pool

Your hit dice pool tracks how many dice you can spend during a short rest to recover HP. A level 5 fighter has 5d10 in the pool. Rolling a hit die during a rest restores that roll plus your Constitution modifier.
