Money Making Strategies for Pure Casters

[Encroaching Death]

So I'll probably have to buy my Necro Epic.

Right now, I can farm about 500p/hour. Is that decent at level 57?

I need to raise about 250k. That's like 500 hours of farming.

I guess I could do CE groups in Seb?

I obviously don't expect people to give up their money making secrets, but is it more efficient to go after big ticket items or consistently grind away at getting smaller, easier items to sell?
