Did you mean special abilities that deal damage and other effects, or visual effects such as explosions?

If you want spesific visual, I'm afraid you have to try and find it yourself. It isn't that difficult, if you streamline it. You can use the same battle to test the effects as long as you restart Dominions, and you could set up a shortcut that automatically opens your test game. If you keep your mod open and your computer doesn't take too long to start Dominions, it's pretty fast.
