Given that I'm a big fan of this mod, q.m., I'd like to suggest you to rethink the "Touch of Madness policy" of making it cost a N gem. While Blink is often just annoying and making it require 1 S gem to cast is great, ToM has some important uses.
If the opportunity that the caster himself goes Berserkr annoys you so much you could maybe consider, if you can, to increase the range. But for i.e. a maenad EA Pangaea this spell is almost a must, even with the chance of some random Pan going mad sometimes, so well... think bout it.
Just a suggestion
I continue thinking the mod is great fun
