the wonderful witches of witches.town have introduced me to the glyph ꙮ
it is "multiocular O", a variant of Cyrillic O that is used in certain religious texts in a phrase that translates to "many-eyed seraphim" and basically nowhere else
I honestly am having a hard time thinking of a single witchier Unicode character unless the Leviathan cross is hidden somewhere in the codeplanes
