Grace Note

You pull on the oath of vengence you have made and harness the power of music to revitalize yourself.

When your HP would drop to 0 it instead drops to 1 and you are able to make an opportunity attack against 1 creature within range. This feature can only be used once per long rest. At level 10 it can be used twice per long rest.

This feature can only be used if your HP is not already 1.
