Yeah, look in the mod folders in pak\mq\maps\heroes\seraphim
There are 3 dds files with the name "seraskin" that can be deleted.
You'd also want to go into pak\mq\maps\heroes\seraphim\sets\mystique and delete any dds files that have "seraphim-mystique-helmet" in the file name,
Most of the mod works this way. Changes not to your taste can be deleted.
Thanks for info.
Cheers,
