Durable Scales (5e Feat)
From D&D Wiki
After several bouts of combat, your scales have adapted to be extra durable and protective when it comes to taking hits. As a dragonborn, your scales fully harden like your dragon relatives and the skin beneath becomes thicker. Due to this, you gain the following benefits:
- Your Constitution score increases by 1, to a maximum of 20.
- When unarmored, bludgeoning, slashing and piercing damage you take from non-magical weapons is reduced by 3.
