Spellmod for the game will be finished in a couple hours. It essentially does 1x cost for levels 1-4, 2x for level 5, 4x for level 6, 8x for levels 7-9. There are a few exceptions. Pretty simple...
As for richness: rich is fine with me.
3x normal food sounds like a lot, though. Is 150% OK? That's a good change... but not a huge change. I want this to evaluate the mod in normal play, to some extent, even though that's sort of already been violated by the magic nerf

.
The final version of the Rebalance mod (7) is posted, and the game-specific level-4-limit mod will be posted before midnight (US Mountain time) tonight. Loks like everyone who want to play is signed up, so I'll take Jotunheim. We just need to choose a map now.
