You're pretty close to being on target, but what you're looking for is the BaseClass column in CLA base. Or, specifically, CLA_gxa, since you're modding Awakening. Since rogues and warriors both use stamina, nothing else needs to be tweaked. A few other notes that may help: When editing 2das you should always do an m2da override for compatibility with other mods. You do this by deleting all of the rows except the one(s) you edited, and then renaming the file from, say, CLA_base.gda to CLA_base_[something unique].gda. In the specific case of the base 2DAs like CLA or ABI you can leave out the "_base" but you usually need the full filename otherwise. CLA_gxa is itself an m2da override of CLA_base. If you want to make the specialization available for both classes, rather than just swapping the classes, when you're making your m2da override, edit also the ID column to a large, unique number. This will make the game see it as a new available specialization. I've done this myself to let my rogue spec as a spirit warrior. :d
