Basically, he wants a ring that will cast the spell Shield. (As opposed to the Ring of Force Shield.) Here's the full text of his request:
Last, as a simple matter of convenience, I would like
to create a unique magic item -- a Ring of Shield, as
the spell cast by a 1st-level caster. This would
require a cost of spell level (1) times caster level
(1) x 2000 gp, doubled because the duration of the
Shield spell is 1 min/level. It would be a standard
action to activate, just like casting the spell, but
would save me from having to use the Divine Magician
alternate Cleric to have access to that spell, which
would improve my abilities as Party Healing Bitch, as
I would then be able to access the Healing Domain.
Is there anything here I should be wary of? I'm assuming he means 1/day "Shield" effect.
