One of my favorite things about Fabula Ultima, and something that I recommend people in other games take a look at, is the Ritual system. The core spells for characters are entirely encounter/combat based. The Ritual system is for everything else. I really like how you can work out how powerful effects that are more story based work in the game world, and characters can do things they need to without sacrificing effectiveness in combat. There's so much to look at in Fabula Ultima, even if you're not intending to run the core game.
