Vulcharc
From Age of Sigmar - Lexicanum

Kairic Acolyte with a Vulcharc.
Vulcharcs are carrion birds so corrupted by the powers of chaos - specifically Tzeentch - that they prey upon the stuff of magic itself. [1a] They are gifted to Kairic Acolytes, upon the arms of which they perch, attacking enemy wizards. [2]
