That's not what I'm asking @Jasonso9

I'm asking you to choose or find a power in any of those categories

Dimensional Phasing/Intangibility: Arwyn has the ability to become intangible by shifting some or all of his existence into the extra-dimensional space known as the Otherworld. When fully phased out of reality, Arwyn is able to enter the Otherworld on his own. He has also demonstrated the ability to pull people into the Otherworld with him. While phased, he is immune to all physical harm, can maneuver through solid objects, and floats weightlessly like a ghost under his own power. Arwyn has demonstrated the ability to phase with split-second accuracy, as well as the ability to selectively phase certain parts of his body.

@Jasonso9 This is my idea

@Jasonso9 I like the power you choose

How about Barrier Magic? It can be used very well and strong

yes it's great

Change it to Spatial Manipulation since dimensional manipulation is a subject of it.
