You have learned to focus your adrenaline into quickening your abilities. As a bonus action, you can enter a surge once between long rests:

While surging, you gain the following benefits if you aren’t wearing heavy armor:

• You have advantage on Acrobatics checks, Sleight of Hand checks, and Dexterity saving throws.
• You have resistance to bludgeoning, piercing, and slashing damage.
• Additionally, when you take this feat, choose one of the following benefits for while you are surging:
  • You gain a +2 bonus to damage rolls whenever you make an attack with a melee weapon using Dexterity.
  • Opportunity attacks against you have disadvantage.

You can’t cast or concentrate on spells while surging.

Your surge lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven’t attacked a hostile creature since your last turn or taken damage since then. You can also end your surge on your turn as a bonus action.
