I would like to see a new weapon skill line where there is no visible weapon.
In the other elder scrolls games you can cast spells without a staff so that seems wizardy.
Or maybe some punches, martial arts moves and casting spells with your hands. Some of the skills could be magicka and some stam based.
There could be a soul gem like item or focus that needs to be quality improved like a weapon with quality, trait and enchantment. It could be holding the power maybe one for each hand slot.
Thoughts?
