The Collected Book of Experimental Might

A collection of house rules and optional systems for fantasy roleplaying campaigns. It introduces a spell progression system covering levels 1 to 20, revised healing and curative magic, and magical disciplines that give spellcasters active powers and ongoing ways to contribute. The supplement also adds the runeblade base class, which combines martial ability with magic without using spells, along with new rules for wizards, clerics, druids, paladins, and rangers. Dozens of new spells, feats, and magic items support longer adventures by reducing the need to stop when spell slots or hit points run low.
