Wyvern variants, including ice and crazy color!
Copy the contents to your module or campaign, then it'll show up as options in the cloth armour variants of the wyvern (the default is cloth option zero). No 2da editing necessary. If you don't want a particular wyvern model, just delete the files for it. You do not need to have consecutive numbers, so you can only use model 2 and 4 for instance, the cloth armor variants only show models that exist. Blueprints are not included.
Because NWN2 uses an n-1 system for appearances in the armor set versus the model name, the model numbers below correspond with
the n-1 variation, so model 5 (files with 5 in their name) is
appearance 4.
model 2: white based for tinting
model 3: dull color with aqua feathers
model 4: icy blue
model 5: vibrant color
