Phaedrus, as soon as we get the cash, I shall be requiring Nightsticks.
No problem. We'll have to get some souls to provide the XP, though. I can get about 200 XP per dark craft/sacrifice (I can get a +64 modifier on Knowledge: Religion, and reroll the check it if it's bad), which is enough for a 5000 gp item, or maybe a bit more if we get fancy with all the modifiers in the BoVD (I could hit +70 pretty easily with those). So we'll need ~100 XP more per Nightstick.
Per the BoVD rules, souls are worth 200 gp, and 10 XP each. Agony is also worth 200 gp, but only 3 XP. A being can provide only 1 soul, but one dose of Agony per hit die. So the most efficient method of "harvesting" XP is to torture creatures to produce Agony, then trade the Agony to fiends for souls, and also use the original victims soul. So, we'll need a "victim" with at least 9 HD to torture, or multiple ones that add up to nearly that, per Nightstick (assuming we can trade them evenly... if we go with the selling stuff at half price, it might not be worth all the trouble, as opposed to just using the Agony and souls we can make).
Of course, we could also try to get some Reliquary Holy Symbols... They're cheaper per turn attempt, but you probably can't just craft them, and they need to be for the proper alignment, unless you can make a DC 30 UMD check...
