They Have A Rudimentary Banking System Here In Mini-Greyhelm
Good thinking Mar. The priest of Isaac, whose name appropriately enough- or irreverently enough- is also Isaac, thanks you for returning their Jug. It's not magical, just sacred. They don't actually have a ton of gps here, but the town of mini-Greyhelm will credit you 6000, nay... 10,000 gp! In goods, training, services, inn rooms, drinks, etc. So don't add any money, we'll just deduct from 10k gp.
You guys each got 3000 xp from that last fight, which is why only the low level guys leveled.
The gold key, the Ocho Glaive, Ocho Belt, and Caveman Kangol are all magical. The key opens the gold lock outside, that's all it does. Worthless to you now, as are probably the demon tailor tools. If you wanna sell the key, you'll get another 2000 in credit, plus 200 gp for the tailor tools, plus 500 for the skull goblet.
The Ocho Glaive is a +8 Glaive! Just kidding. It's a +1 Glaive, +2 vs. good-aligned creatures. (Worth 5000 in credit.)
The Ocho Belt is a Belt of Skeleton Control. You can automatically command skeletons as a 6th level evil cleric, plus Animate Dead once/day, plus Summon Skeleton once/week. (Worth 3000 in credit.)
The Caveman Kangol is really a Hat of Evolution, which is +1 IQ.
