This effect will reflect the next effect delivered with the Spell qualifier cast at the recipient back at the caster, including beneficial spells, after which it is used up. The recipient must say “Reflect Spell” to inform the caster that the spell was returned. It does not protect the recipient from the Magic damage effect or any other qualifier such as the Weapon qualifier.
This spell lasts until used or affected by Dispel and cannot be used in conjunction with a Spell Shield. If you have a Reflect Spell active, you may still “accept” spells that are touch-cast, though you must be conscious to do so.
