The whole time I've been testing my game, I've been changing balance, even to the point of overhauling damage formulas. I think it's getting better, but I won't really know for sure until I open it up to a wider group of people. Even then, I know balance is quite the subjective thing and I hope to err on the easy side.

The main issue I've been running into lately is that the Mage levels up so fast because once they have access to spells that damage multiple enemies, they are able to deal a fuck ton of damage. To ease this, my most recent change has been to make the multi-enemy spell use the same formula as the level 1 version of the spell instead of the level 3 version of the spell.

I also nerfed spells across the board, sort of... made them more reliant on the level of spell you're using instead of the level of your character. Previously, both the level 1 and level 4 versions of spells would do nearly identical damage if you were a high enough level, since the damage bonus they offered meant less and less. Now, it just uses a straight multiplier of your magic stat instead of a bonus that is added on to your magic stat, and although it is technically a damage nerf it should make deciding what version of a spell to use a lot harder. If I need to increase the damage the spells do, I could just always make the multiple a decimal instead of an integer.
