Arms Change

You create an extradimesional space within a distance that your character can reach. The space is 1ft wide and 1ft tall. You may store a number of weapons within the space equal to your spellcasting modifier. When you cast this spell, the space will allow you to retrieve one weapon of your choice that is stored within the space. Alternatively, you may swap one weapon within the space with one not currently within the space that you are holding. If it is a weapon that you are able to attune to, you instantly become attuned to it.

At Higher Levels.  When you cast this spell using a slot of 6th level or above, you can cast this spell as a reaction or retrieve 2 weapons at once.
