Include Attune Gate (FiD)

Starfox's Blades in the Dark fan page

There are things that are possible to do here that are not allowed in the regular world. Appropriate effects are reduced one step in difficulty, from advanced to basic, master to advanced, and apex to master. This opens the possibility of new super-apex powers that have to be negotiated with the game master. Such effects rarely reach outside the plane of origin, but if they affect creatures there the effect may remain when you return to the mundane world.

This can be sued to gain access to creatures too powerful to summon, so you instead ask for an audience. This allows you to ignore tier when creating the gate, but gives you no power over the target. The creature may then use the gate to come to you, call you into its presence, or just communicate with you.
