This is for the x-pack, for those who do not yet know, so you people wont look everywhere for the stat changer in the trigger effects because of the name difference. The trigger is called Modify Proto unit, NOT change unit stats or something like that. I do not think you can change an individual units stat other than its name. Modify Protounit changes the regular stats of the unit like HP, Att, armor etc. It also changes the bonuses that a unit has so you can have an archer have a 5X bonus vs cavarly, also you can change how many arrows an archer fires, for example I had a toxote fire 100 arrows at once killing a collosus in seconds. Secondly you can change the healing rate of a unit, also other changes you can make to a unit is its cost, how many pop slots it takes, you can also add a lifespan to it like a minion. I'm pretty sure if you change one toxotes stats it changes all of the toxotes stats. Well this was just a message to tell people the trigger is called Modify ProtoUnit, and what it can do.
