you gain the ability to manifest a mark on your face, called a demon slayer mark, for a short time. Marks differ in appearance, ranging from fire like patterns spanning across the face, to a small wind symbol, dotted on the cheek. At will, you may manifest your mark, granting you the following benefits for 1 minute:
- Your movement speed increases by 20 feet
- You gain a bonus to melee attack and damage rolls equal to your Strength or Dexterity modifier +1
- You gain the ability to use a reaction to reduce damage by 1d6 (increases as you level lvl7 1d8, lvl12 1d10, lvl18 1d12)
- You gain resistance to bludgeoning, piercing and slashing damage
- You can see into the transparent world. You have advantage on your attack rolls, and attack rolls against you have disadvantage. You can also determine how physically well a creature is, thus allowing you to know how many hit points a creature that you're looking at has remaining.
- Add 1d4 (or d6 at lvl10) to your breathing technique damage
You may use this feature once per long rest.
