Quick Questions

I am playing a 1.1 game as the Priestess and have a few things I need cleared up.

How do you use her Destinies Favor points to cast spells?

I allied with Imperium and they gave me Sundros the Avenger for a hero.  He has an empty weapons slot, but I can't find any weapon he can equip.  Does anyone know what weapons he can use?

Also, he can use vengence points to do things, but I don't know how he gets vengence points.
