Oh and I really don't want you to go through the trouble of extracting 3000 files. It's too much work. I just wanted to make an angel summoning spell ( bye, bye Telestic Animation no one loved you! ).
I suppose Telestic Animation would be useful for Ermor were it not so high up the research tree. And maybe if you are getting dominion crushed it would be useful. But I think that a lower level ( 4? ) spell that could conjure a single angel for something like 5 astrals would be more useful ( Zen's Angels that is the garb and attack really help ).
I have been using that method when I have needed to get graphics from the gam. I have had both Dominions and Paint open, tried to zoom the lone attacker to about the same size as his spr1 open in the paint, then screencaptured etc.
I normally get a test game just for catching that sprite, and sometimes I make a quick mod that adds that unit type a ranged weapon like Mind Burn. That makes it much easier to catch him alone.
You can also (as I do) make your own attack .tga files. A good way to this is using the option called 'rotate the layer or selection' in gimp. Just mark eg. the arm and rotate it. Sure you need to patch it and make some minor adjustment afterwards, but the result is rewarding
