The following creatures are unavailable and I'll have to figure out replacements. Some can perhaps use existing models. Is anybody interested in trying some of these reskins? The ones in italics I'm stumped at present.
- Allip -> Perhaps a wraith with a modified skin or effect?
- Aranea -> A Giant Spider should do
- Battle Devourer -> Intellect devourer reskin?
- Beholder Tyrant -> Perhaps a modified beholder?
- Deva -> aasimar with wings, I guess
- Cockatrice -> maybe a basilisk?
- Ettercap
- Ettin
- Ghost -> can use an effect
- Harpy
- Helmed Horror -> can use the invisible person model
- Hound Archon
- Magma/Steam Mephit -> have the first; can build the second
- Medusa
- Mephistopheles -> I can always resort to a Balor, I guess
- Mohrg
- Mythril Golem -> one of the custom NPCs is a unique-looking golem, so maybe that will work
- Revenant
- Shadow Fiend -> should be able to build this
- Shield Servant -> should be able to build this
- Shocker Lizard -> reskin of the lizard/dinosaur with an electrical effect?
- Tyrantfog Zombie -> pretty much a zombie with a gaseous area effect
- Vrock
- Winged Elf -> elf with wings added?
- Wraith Spider -> maybe a giant spider reskin or effect
For the tyrantfog zombie, you can use either a ghast (since they already have the effect), or the Drowned.
The shadow fiend on the nwn1 wiki looks like you could either use a shadow minus the effect or the nightwalker (since they are the same basic model, just different eye coloration and the nightwalker looks a bit more hunched over), I did white base versions so you can tint to your preference
Vrock: faezressparlkes has shown a vrock in their creature compilation.
Ettercap: also faezressparkles.
Hound Archon: gnoll/thayan gnoll
Revenant: any player race as they are basically normal humanoid looking except for their normally grey skin color. You could use the male vampire model too.
Morhg: a retexture of a skeleton, since the mohrg is basically a skeleton with guts
deva: a human with wings, alternately we have the Solar model.
beholder tyrant: tint a beholder and be done with it.
allip: wraith (I've released white wraiths, so you can tint these guys as you want)
shocker lizard: snake? We have a snake model.
shield servant: unsure what they look like but how about invisible human with a shield, like the animated armors we have.
cockatrice: scaled down wyvern would look very much like one, also I've done retint versions of the wyvern.
harpy: there is a good quality harpy for nwn1 that PhoD did this month. It could be converted. Alternately, the stirge model (because it flies).
