As it turns out, Divination spells are pricey.
I need cash, and a lot of it. For one spell. One spell in the tune of 30,000 Gs. I've liquidated all my gems and magical items that I'm not using; I'm even doing some mercenary job for Eliath for about 1500 Gs; How else does an adventurer come up with a hefty sum of gold in Waterdeep? This is Waterdeep, City of Splendors, there must be a way, right?
