Stickers

Stickers are character-modifying items that can boost attributes in battles. Stickers come in two types: Normal Stickers and Colorful Stickers. Normal Stickers apply stat modifiers to the character, while Colorful Stickers let the character use new or modified abilities. 
== Sticker Sheet ==
To apply stickers to a character, they must be equipped through their Sticker Sheet. The number of empty slots on the Sticker Sheet are based on the character's level. At level 10, all Sticker Sheet slots are available for use.
== Sticker Upgrades ==
Unlike Colorful Stickers, Normal Stickers can be leveled up and have their stat bonuses increase based on the current level. All purchased Normal Stickers start at level 1 and can be increased up to level 5.
