Bug's Control Chaos

You attempt to halt an ally who is about to do something you deem "a stupid idea". When an ally within 60ft of you uses an action to make an attack, use a damaging ability or cast a spell of a level equal to or less than your spellcasting ability modifier +1 (minimum of 1), you can use your reaction to force an INT saving throw. On a success, the ally flips you off, and nothing happens. On a failure, the ally wastes it's actions that turn doing nothing.
