There probably isn't an equivalent tag to "Hero.Arcane" or "Hero.Divine". One option you could do though is create a script on one of the existing conditions (ie Blinded) that looks through the classes and assigns something like "User.Warrior" to any classes you want it assigned to. You can then use that tag as your pre-req.

To do this you would have to create a replacement condition, but that should be pretty easy I think.

Or I guess you could just make a really long pre-req string like "Classes.Barbarian | Classes.Fighter | etc"

Or another idea: look for the cAttack.Good tag on the cHelp things.
