Who uses Unsealed Spellbook

Pick rate is measured inside each champion-role sample. Share shows how much that champion-role pair contributes to all observed uses.

Champion	Role	Pick rate	Win rate	Share	Games	Analyze
Alistar	Support	12.9%	52.4%	16.8%	940	Build Lab
Twisted Fate	Middle	11.3%	50.4%	16.1%	903	Build Lab
Rakan	Support	14.3%	51.1%

These are descriptive outcomes from completed Ranked Solo/Duo games. Build timing, champion strength, player skill, and game length all affect the result; a higher row does not prove the resource caused the win.
