According to the latest 10.1.5 PTR patch notes, Sayaad and Infernal customizations will be added in a future build, although by looking at the current customization options, you could say that the Felhunter, Felguard, Infernal and Doomguard are also lacking substantially.
One thing to note, the old demon-changing glyphs have been changed into Grimoires in Patch 10.1.5, and can be used to teach their specific appearances at the barber shop:
Imp Customizations
Imps have the most complete customizations, with 15 customization options available for players, coming from a variety of sources.
- Customizations 1 through 4 are recolors of the converted Grimoire of the Fel Imp, but learning the grimoire will only teach Customization 4.
- Customizations 5 through 11 are recolors of the original Imp, with Customization 5 being the default Imp skin.
- Customizations 12 through 15 are taught once you complete the special Warlock questline in Patch 10.1.5.
Felhunter Customizations
Felhunters currently have 5 customizations available for players, with 3 of them having known sources. As of note, unlike other form changes, the Glyph of the Observer is being removed in Patch 10.1.5.
- Customizations 1 through 3 are recolors of the original Felhunter, with 1 being the default Felhunter skin.
- Customizations 4 and 5 are felhound-esque customizations, and their sources are currently unknown.
Voidwalker Customizations
Voidwalkers have 9 customizations, with almost all of them being available by default. 2 Voidlord customizations are unlocked when learning them via the converted Grimoire of the Voidlord.
- Customizations 1 through 3 sort of bring back the old Voidwalker model from before Legion! They have the same low poly blackberry body, but they have shoulders instead of the bracers from the old model.
- Customizations 4 and 5 are the Voidlord customizations learned via Grimoire of the Voidlord. Unfortunately, as of this PTR build, your Voidlord name is lost even when picking these customizations.
- Customizations 6 and 7 are similar to the old Voidwalker models, but they have void effects sparking through their body!
- Customizations 8 and 9 are the default Voidwalker model post Legion, with 8 being the default skin, and 9 being a version without bracers.

Sayaad Customizations
Sayaad customizations are currently incomplete on the PTR, but there are 5 models to choose from – The customizations learned from glyphs.
- Customization 1 is the default Succubus skin.
- Customization 2 is the old Glyph of the Shadow Succubus, now converted into a grimoire (Grimoire of the Shadow Succubus).
- Customization 3 is the Fel Succubus from Orb of the Fel Temptress, a rare drop from sayaad mobs in Cathedral of the Eternal Night.
- Customization 4 is the default Incubus skin.
- Customization 5 is the Shivarra custmization from the converted Grimoire of the Shivarra. Your Shivarra will have its name converted to that of your female Sayaad as of this PTR build.
Felguard Customizations
Felguards currently have only two customizations on the PTR – The normal and Wrathguard forms. You must be specced into Demonology to be able to see and choose Felguard customizations.
- Customization 1 is the default Felguard.
- Customization 2 is the Wrathguard from Grimoire of the Wrathguard. As of note, your Wrathguard will lose its Wrathguard name as of this PTR build. You can also finally combo the Wrathguard with Glyph of Felguard to allow it to wear two-handed weapons in your bags, but your Wrathguard will only wield 1 weapon while under the effects of the glyph.
Infernal Customizations
Infernals currently only have two customizations on the PTR – The normal Fel Green infernal, and the orange version seen in Infernals in places such as Blade’s Edge mountains. You must be specced into Destruction to be able to see and choose Infernal customizations.
