AstralLevelTweak - Spell Experience Customization
This mod provides the ability to completely change the experience calculation formula for perk levels in the Astral Sorcery modification. You gain full control over how experience is awarded for magical abilities.
For creating custom formulas, you can use all mathematical operators and functions described in the DoubleEvaluator documentation, as well as two special variables: i (current level number) and prev (experience from previous level or 0).
The mod was originally developed specifically for the Multiblock Madness modpack, but can be used in any modpack containing Astral Sorcery.
