Illandril's Character Class Enhancements (5e)

(formerly "Illandril's Pact Slot Third Caster (5e)")

Adds support for alternative Spell Progression types (including Third Caster Pact Magic, Three Quarters Caster, and more), and allows a d20 option for hit dice.

The specific rounding mode for Pact and Leveled progressions can also be configured if the default rounding (round down when multiclassing with multiple spellcasting classes, round up otherwise).
