How would I create a shape-shifting hero?

[Hubert Cumberdale]

I'm fairly new to this. Obviously, the permanent Illidan metamorph ability is one way to 'shape-shift' between forms, but how would I create more shape-shifts for a hero? The Raven, Bear, & Crow Form seem to be a non-option, since they cause all kinds of glitches on a hero (as they were made for units)
My maps are, at the moment, Reign of Chaos ONLY, so that I can accustom myself to the basics.

Well, the easiest way would be to copy metamorphoses then edit all the hp, dmg and model values to your liking . By the way, you asked for help on the wrong thread, next time you need help, go to the "World Editor Help Zone."
