Well, as I wrote, the unit stats are located in GameMecanics/Creatures... there, the characteristic files are sorted by faction folders, one file per unit. Frankly, I don't see the point in listing the contents of these files line by line. First, there are the numerical characteristics - attack, defense, health... it ends with danger and experience, then the price, and at the very bottom are the abilities (there are no ranged attacks, spells, or flight; you need to specify these in the first numerical block by giving units spells and projectiles, and there is a separate line for flight).
By "visuals," I meant animations. Units can have casting, shooting, and ability animations. For example, a druid has all these animations, but a gremlin doesn't have a casting animation, and when casting a spell, it will stand in a T-pose. There was also a funny bug in the WGE mod - a gremlin with a stunning ability would play the repair animation every time it stunned an enemy; you also need to keep an eye on that.
