In the canon spell it's a circle 2 spell, but only affects non-magical armour. Not sure if that can be scripted when all armour will have properties (value properties). I'd suggest 3rd or 4th circle so it has to compete with other strong transmutation spells like Slow and Polymorph. DC could be reduced depending on the weight of the target's armour, so it's harder to remove fullplate.
