Quake damage is same at all levels

Version 0.6.0

I'm fighting Gargantua on top of the Dollet Tower (seed 1117253956), and his attacks are properly rebalanced. However, he can use Quake, which does over 1000 damage to everyone in my party, which is an instant wipe. Perhaps some editing can be done to this spell, to make it dependent on magic power?
