The Knight's Instant Armor.

Target instantly dons a target suit of armor.  Both Target and the Armor must be within 20 ft of the caster.  If armor is placed on a character who is not proficient with that type of armor they still suffer penalties as appropriate.  If an opposing character is targeted by this spell,  it must make a Strength Saving Throw or it will don the target suit of armor.  The caster may target himself.  For every level above 2nd the caster may target another character within 20 ft and another suit of armor.
