how should i run duchess? Ive never been big into casting and spells, and whenever i do its always hybrid, but i cant seem to get duchess to work? Should i just aim for a quick spell like slicer and a dagger that has frost/bleed or something?

Alright I picked this up today and really liking it, but im playing offline. Any general advice on how to not be a retard in groups? I dont want to ruin my teammates games (they'll probably do that on their own just fine)
