Terrain Savvy
Wisdom 13 or higher
You make the best out of any battlefield, and take any moment
you can to catch your breath in the middle of a skirmish.
- Half cover counts as three-quarters cover for you.
- When you gain cover from a hostile creature, you can spend a number of Hit Dice up to your Wisdom modifier to heal yourself. Roll the dice, add your Constitution modifier to the result, and regain a number of hit points equal to the total (minimum of 1). You must finish a short or long rest before you can heal yourself in this way again.
