I've seen some comments about Spells/Powers/etc not having damage and while this is basically true you can drag them to your Abilities and open the "Triangle Icon" to get most of the details you need. Because most of these have damage that changes based on effort put into them (read energy or whatever) you would need to calculate that for each use.
Giegerman mentioned setting them up as weapons (melee/ranged) and then you could create modifiers to indicate how much effort you used and just use that attack damage. I think this is how I would do it.
If there is some way to make this better let me know and if possible I'll see what I can do.
