A physical injury in your past has affected you on a psychological level.
You gain a new ability: Suppress
As an action you can start concentrating on keeping your wound suppressed as if you would concentrate on a spell.
If you are concentrating on keeping your wound suppressed you are "Suppressing".
If you are not currently Suppressing you gain the following drawbacks:
- If you use more than your Maximum Movement Speed - 10 ft you have to make a DC 10 Wisdom Saving Throw. On a failed save you clutch your wound in pain.
- Additionally if you fail the wisdom saving throw you lose all your movement on your next turn, unless you use your action this or next turn to Suppress.
