• Once per round, if you would use a Bonus Action to command one or a group of constructs (such as a Homunculus or two Eldritch Cannons), or one or a group of entities you created with a spell from the Artificer's spell list (such as Tiny Servant or Animate Objects or Bigby's Hand), you can do so without expending your Bonus Action.
• When making a Constitution check to maintain Concentration on an Artificer spell which has created/summoned entities you can command, you have Advantage.
