Bloodlust

You've spent enough time with blood on your hands, you've started to relish in it

Increase Strength by 1, up to a maximum of 20

When you kill a humanoid with a melee strike, the scent of blood energizes you, and you may activate this feat. Heal 1d4 health, and for the next 2 turns, you may make a 1d6 Unarmed Strike as a bonus action. Killing another humanoid refreshes the duration, and heals you for another 1d4.

Alternatively, you may heal 1d6 health and gain resistance to piercing and slashing attacks. This will take the place of your Unarmed Strike capability.

This effect ends after you fail to get a humanoid kill in the time limit, and cannot be used again until after a short or long rest
