1) What are Belldandy's, Skulds and Urds powers?

Beldandy: I'm a bit vague here. Your typical magic spells.
Urd: Potions and stuff like that. Mostly love potions of some kind ;)
Shuld: All things machanical. 

Actually, that's just mental intellect. She has the power to write "BAKA" on
any surface (or something like that) I think that if she writes it really
large, it hits with some force. (And it doesn't come off.)

2)How do they travel?(I heard they travel by diff means.)

Bel: Mirors.
Urd: TVs, monitors and the like.
Skuld: Don't know. I don't think she can.

She travels by using liquid mediums.
