Unable to enchant any of the following on an Enchanting Vellum or an appropriate weapon, in this case, Billowing Magmathrower’s Cudgel, which is a mace, for a guild member. Burning Writ, Earthen Writ, Frozen Writ, Sophic Writ, Wafting Writ. Whenever trying to enchant the error “The spell is incompatible with your weapon appearance.”
Removed the Transmog of my weapon and was able to do the enchant. I don’t think that MY weapon transmog should affect the ability to enchant an enchanting vellum or someone else’s weapon. My weapon is the Searing Blazecaster, the current appearance of it is Arathar, the Eye of Flame.
I can see that this could really get someone stuck if they are trying to level their profession.
Edit- Added solution that allowed the enchanting process work
Edit- added the item being enchanted, added my weapon and what its transmoged as
