Good one handed weapon for mages?

[Zen]

You can try another shield (it never hurts) if you are going to go for something fun and are facing alot of SC's or elite armies (at this point) try Totem Shields.

Also if you don't have access to good undead nuking spells, a Herald Lance is always a good pick (with Standard). Summer Sword for Tangle Vines (again, if you are facing some SC's).

Faithful as a main weapon then a Shield of Gleaming Gold isn't too shabby if you are dealing with things with morale.
