At 20th level, you gain the ability to harness extraordinary martial prowess. As an action, you can magically become an avatar of conquest, gaining the following benefits for 1 minute:
- You have resistance to all damage.
- When you take the Attack action on your turn, you can make one additional attack as part of that action.
- Your melee weapon attacks score a critical hit on a roll of 19 or 20 on the d20.
Once you use this feature, you can't use it again until you finish a long rest.
