I've been getting runs in the Cathedral of Flames quest in Doomlore Shrine. They cost about 3k, but you get 1.75k from the quest and lots of golds tend to drop, plus the chest at the end. I've gained two deldrimor ranks (I'm half way to 6th now) and have made enough money to buy some 15k armor from 10 to 20 runs.
if you are still only rank one you probably just started eotn, so to get to the dwarven armor maker you got to do the entire game anyways, just give the dwarves your heroes hand book and you will be rank 5.
When doing Snowmans in HM and u want to Hero/Hench it bring
3 Monks, 2 Nukers, 1 MM, & 2 Tanks
Bring the 2 Monk & Tank henchies & Monk, Nuker, & MM heroes.
If your using a ranger you can try switching out a tank or nuker.
Theres about 5 chest per run so bring lockpicks, you will pretty much make all your gold back from the drops.
wasting a hero's handbook on dwarf points is a pretty bad idea. Thanks to the snowman dungeon the dwarf title is by far the easiest to max out.
Since the OP didn't indicate that they wanted to max the titles, just get the armor, was why I said to just turn in a hand book. Not everyone wants to max those titles.
