Primal Fighter (5e Feat)
From D&D Wiki
Prerequisites: Proficiency in Unarmed Attacks.
After a long time of combat training, you have gained the ability to tap into an animal-like rage when you attack, making your unarmed attacks far more powerful than ever before.
- The damage die of your unarmed strikes increases by 1 size (1d4 becomes 1d6, 1d6 becomes 1d8, ect).
- If you deal slashing or piercing damage with your unarmed attacks due to using a sharp object on your body (Talons, Claws, Teeth, Spikes, ect.), the creature you hit with an unarmed strike must make a Constitution Saving Throw or be Blinded until the end of their next turn. The DC for this saving throw is equal to 8 + your proficiency bonus + your Strength or Dexterity modifier.
