You replicate the effects of armor by using a piece of it as a magical focus. This protective magical force shimmers faintly around you, taking the shape of the armor from your focus component. The spell ends if you don armor or if you dismiss the spell as an action. The spell has no effect if you're already wearing armor.

The strength of the spell is dependent on the spell slot used and the focus material component required to cast it. Spells cast at a higher spell slot than what the focus material requires retain the spell effect directly associated with the component. Refer to the table below for requirements.
