Config Info
The mod is highly configurable. You can edit config values in-game and during runs through Settings -> Mod Options -> UmbralMithrix. Stats are calculated at the start of each phase so if you're blasting through Phase 1 you can make the other phases harder. If the in-game values are too limiting you can edit the modman config to input custom values.
