Runes

Every magic spell spends runes each time you cast it.

1. 1Basic: earth, lightning, fire, light and water. Sold at the shop.
2. 2Catalytic: needed by higher-level spells.
3. 3Combination: each counts as the two runes it is made of.
4. 4Primal: only the biggest spells need it.

Shouts and techniques never spend runes.
