"Why not? Traditionally magic has often been conducted through musical instruments, and Necromancy in particular is known for employing bells and sundry summoning instruments."

And in the same way a rogue, regardless of whether they actually are a thief, is called a spellthief when their performance is bolstered by magic.

"Regardless of that excellent but futile little ideal of yours on that point, they are, beside metaphors and idioms, the single most effective way to lead someone to a conclusion. NOW! A spellsword is most likely to become a militant undead, yes?"
"Wraith, Revenant, Draugr, Mordicant and the rest. Yeah."
"A spellthief would become a lurking, lying, charming sort of undead by the same token?"
