Shattered Kingdoms

Magical vestment is a surprisingly effective defensive enchantment that
can benefit anyone who is wearing clothing or light armors that are able
to be repaired at the tailor shop. The spell will magically toughen
those pieces of equipment, increasing their protective value proportionate
to the power of the caster, for the duration of the spell. Even initiates
find this spell useful though, as it prevents harm from physical damage to
the affected pieces of equipment regardless of caster level.
