Spellblade

Spellblade was a magical quality that could be applied to weapons

It made the wielder immune to a single spell of the creator's choice, but only if it was directly targeted at the wielder, not those that affected a large area. The spell was absorbed by the weapon and the wielder could then choose to redirect the spell at a target of their choosing, or let it drain away.

Creation of a spellblade weapon required a spell turning spell.
