Anyone know the file that has all the attack types?

You know like how Piercing does 75% to small armor and 150% to large armor. I would like to change the values for some of them for a specific map, anyone know which file contains this?

I also would like to add a Spell attack. Its listed in the World Editor, but in-game it transforms to Normal damage instead. I want to find a way to activate it and set damage properties for it if it doesn't have any already.

the armor and dmg stuff is in miscdata.txt in Units, so sorry that can only be changed for single player maps
