Enchant

Enchant is a keyword ability that restricts what an Aura can target and be attached to. Aura is an enchantment type.

Description
Up until Ninth Edition of the Core game, Auras were known as "local enchantments". They said "Enchant (object)" - where (object) is what it could enchant - instead of "Enchantment." Thus, local enchantments carried all the rules in their type, which agonized R&D. Now that the rules are in the actual text box, Auras can be more diverse and it's easier for beginners to recognize that Auras are enchantments.
