Reverse Recovery (Japanese: 治癒の術を逆転, Kanji translation: Recovery Technique Reversal, Romaji: rikabarī no jutsu wo gyakuten)[1] is a white magic spell. Lina Inverse created it as a variation of the Recovery spell.
Used against trolls, the spell reverses the innate healing powers these creatures have, so instead of healing any wound, it would expand it until it kills, or even completely destroys, the creature.
