And because Loki starts with Chaos II
I personally really don't like mutation as an arcane spell. I'd rather bring back one of the best summoning spells, summon Chaos Marauder (with its good chance to turn barbarian). Naturally, Loki would probably need to lose the choas 2 promotion.
My modmod will increase the number of Divine spells, but make them require a state religion. I'm letting you build priests of any religion, but they won't have access to their spells unless you convert. I could bring mutate back as an OO spell, but I'm leanign against it. Tsunami is already really good, and (since letting everyone have water walking priests) I'm probably going to make water walking a spell again (I'm probably going to make it give a temporary water walking promotion to all units on the tile). Hmm...I guess I could make Tsunami stringer and give make it Speakers' second spell.
I've moved Cure Disease to Medic 2 (from Divine/Channeling2) and Heal to Medic 3 (from Divine/Channeling 3), in part because I don't like Grigori Medics having Divine/Channeling (especially when combined with the the new "And Now for Something Completely Different" Grigori-specific, Hero spell) and in part because the mouseover for Divine is too large (and is getting larger in my modmod. I'm considering making the Evil religions' priests have different healing spells (probably replacing their medic promotions with something else) which also cause mutation, and make diseased units into disease carriers instead of curing them completely.
