Yes, through a Necromancer, in about an hour. He's a bit inconvenient, but spirits under a Vampire are worth the effort. I also spent a long time accumulating mercury for the Guild because I had none. There's a nuance in the internal "hamster" (resource management) of the game. For example, mana cannot accumulate beyond a certain limit, so while it should be conserved, players shouldn't be afraid to spend it. But runes in the original game, or runic magic, or units – these are not limited resources that deplete, and they accumulate, so each loss is felt acutely. I once even read an article about the psychology of ammunition for a "super weapon" in shooters. And another point, I played with luck affecting the path and loot, so I wondered, when I got, for example, 20 gems and 12,000 gold after a battle, was that intentional?
