It's a Debuff spell. Makes the target's spells cost more MP. (+15% more at max level.)
Ahh that answer that. I was hoping it would be a like a mirror shield spell that reflects the magic back on the caster. But that might be too overpowered.
Well, Ellie... I got all the spellbooks.... Now I just need the SP to get them learned and upgraded to full level. Six of one, half a dozen of the other, eh? I'm down to 2500 SP lol and so I got some grinding to do to even get the skill. Wanna trade me SP for the spellbooks? haha
[In case you don't know, it drops from the Elder Lost Watchers. My SR spent about 2 hours there last night and got it.]
