Nice Mod, Im looking forward to it. The Slam Power really caught my eye, and the same with the teleport.
You said in one of your videos that you were thinking about making some spells for stealth characters.
Well, heres a few ideas:
Dim Lights: It would have a stronger effect the longer you channel the spell, and what it could do would make the room you're in pitch black but give you some sort of detect life or nighteye spell. It would, however, alert the enemy of your presence. You could then make a swift escape (if you were being chased), or a swift assassination.
Smoke Cloud: Does exactly like it sounds like, summons a smoke cloud in front of you. It would stun the enemy and provide brief cover in which enemies can't see you, allowing quick backstabs or a flurry of attacks from all directions. (This one might be too much like the stun move you have with Air Bending, but variety IS nice)
Dark Blades: This would basically summon a blade (It would be cool if it was a fist weapon, or if the summoned weapon was dual wieldable) that has bonuses when used in unison with another one of theses Stealth powers. Example: If I dimmed the lights, and attacked with the Dark Blades I would get a significant damage bonus (Maybe just 1.25 or 1.5 so it's not unbalanced). And if I sneak attacked while the lights were dimmed, I'd get the normal sneak attack bonus plus the Dark Blades Bonus.
Just a few, I might come back with some more ideas later.
Keep it up, looking forward to it!
