Teleport? There was nothing there about teleportation nor fly.
And for the disarming and catching things, it really matters about how much light is there, and how much shadow is already there.
Point is, it has been exploited in the past and I don't want a total repeat of what happened then.
Okay, fine, I will allow it on one condition. This is a very risky power that I don't enjoy having in roleplays, so at the slightest hint of exploit I will call you out. No argument if I call you out for it. If you accept these very strict terms, then yes you may have this character.
