Seal

		"You belong in a museum!" This article or section may contain obsolete information, but exists here for historical purposes.

Seals are the yellow runes. They have physical and magical defensive boosts, which are very useful to squishier champions and tanks alike. There are no Seals of Scaling Cooldown Reduction, Armor Penetration or Magic Penetration. There are 24 variants of seals.

The Seals are represented in three forms: a chalice, a shield, and a wing.
