Also, for levelling up, how about you can Level Up only if you have spent at least [s]1 MP[/s] [b]Might equal to your current level[/b] on something else since your last Level Up (including at the start of the game).

This work?

The trouble is that will more than double the amount of Might it takes to Level Up at the current proposed costs.

A suggestion: our goal with this is to encourage Might spending on useful stuff rather than on power-levelling, yes? What if, instead of spending Might to increase your Level, you Level Up whenever you spend your Level's worth of Might on things other than Holy Sites, Domains and Portfolios? (The exact quantity of spending needed could be rebalanced, of course.)
