This guide will have all gifts documented for all characters. Some characters will have spoiler tags as they appear later in the story. Be wary of hovering over spoiler tags, if you want to avoid (mostly) minor character spoilers. Especially the final two are heavy on spoilers.

Also, if you don't have access to certain gifts, don't worry. With more access to the overworld, collect the rainbow chest squares whenever you can, they will give you the prerequisites to craft new gifts. Some gifts are locked behind story progression, like Dark Glasses. Just play as you would normally, you'll eventually unlock them.
