Hello mods! I have a question in regards to powers!

In FFXV, the characters can actually access a hammerspace for things like weapons/items/etc. Would this... still be a thing?? Or would it be limited to like their own posessions/weapons? Or would they be unable to access it entirely?

I just wanted to check because i'm sure it has the potential to be OP, and I didn't know if it would be nerfed or not before I started referencing it in the tdm, hahaha.
