You command one of your summoned creatures you can see or otherwise detect with a Precise or Imprecise Sense, allowing them to take actions on your turn. You cannot target a summoned creature with this action that you did not summon yourself.
The targeted summon gains 1 Major Action and 1 Minor Action which it can use to take basic actions, such as Stride, Step, Strike, Hide, Climb, Swim, Seek, Grapple, Trip, etc. It cannot use either of the Inspiring Words or Gather Power actions, nor can it use any abilities that are normally granted by Feats.
