Lord of Blades hates/despises all fleshies, so...
Why not change the auto-slot-heals on WF clerics to, and add to the divine spell list, repair spells for WF worshipping LoB? A WF healer that worships LoB, would naturally use repair spells, as they extremely dislike fleshies, but maybe not hate, they wouldn't carry 'cures' any more than most fleshy healers carry repairs. These would be divine spells, making them susceptible to quells, but also able to be cast in armor naturally, which makes sense as WF often have mithril or adamantine, and LoB wouldn't change that, right?
