shapeshifting problem

hey can anyone tell me how to make a nightelf turn into a panther instead of a bear i have the panther model and now i dont know how to put it so the nightelf girl turn into a panther

You need custom models

Or if you dont mind it being ugly, modify one of the existing morph abilities. LOok for Bear Morph in the Night Elf section of the Ability Editor for an example.

The special effect trigger actions could be used to obscure the ugliness with large glow-ey effects.

If you need more specific help i encourage you to check out some tutorials and general World Editor use.

nvm i got it working now how do you put stocks? for hero choosing whenever i try it said "out of stocks"
