Spell levels
Spells earn XP each time you cast them and have their own upgrade trees, and a spell that is behind your highest-level one earns double XP. They go up to level 6, which takes 120,000 XP in total. Getting any spell there earns Playing With Power, which 19.3% of Steam players have. The XP planner works out what a spell still needs.
Each spell level above 1 grants 1 upgrade point; each upgrade costs 1 point, so a level-6 spell holds 5 of its 8 upgrades. Levels 2 and 4 are pick-one-of-two; the level-5 upgrade follows the level-4 branch; levels 3 and 6 follow either. Picks can be swapped for free in the Spells room.
You take 3 spells into a stage. Spell Rush drops the heroes and speeds the spells up, and Hero Party takes spells away entirely.
