Celes [Final Fantasy 6] have an ability: Runic/Unicorn (in Pony Fantasy 6): Absorb once per turn all the MP used in a spell without care if’s healing, damaging, status or casted by enemy or ally (and prevent that spell for hitting anyone or causing the intended effect).
 
Twi casted Thundara spell (a level 2 spell) but Celes recover MP and get no damage instead.  
Twi’s impresionated with an Unicorn capable of Absorb magic (and nullify damage), think Runic ability’ll be useful against Tirek and Discord but forgoten’s pretty useless against non-magic abilities like throwing a Fuuma Shuriken or devouring manes.
 
The only problem’s Thundara only use/cost 22 MP and those 6740 are way far from 255 max MP-cost per spell and 999 max MP-pool per playable character, only non playable characters like Bosses have a 65535 max MP-pool (but the highest’s Kefka 60000 MP-pool).
 
Also Twi forgoten the Changeling attack for they hyped with Celes’s Runic.

I dunno, all I know is that the changelings think that manes are delicious.

Um… what’s happening?
