Limit breaker

You can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action on top of your regular action and a possible Bonus Action.

Once you use this feature, you must finish a short or Long Rest before you can use it again. Starting at 11th level, you can use it twice before a rest, but only once on the same turn. At 17th level you gain a third use before a rest, but only once on the same turn.
