Okay, heres the deal.

For Skorms Bow, get either the mercenary at the Tample of Avo or in Twinblades camp(I got the one at Twinblades camp) and take them to the Chapel of Skorm. If you noticed, the Mercenaries take their pay every hour, but the trick is timing it right. Stand near that temple guy at night and watch your clock. When it looks like its going to be midnight soom, look down near the bottom right corner of the screen. As soon as he takes his pay, talk to the Chapel guy and he will sacrifice it and it will say "you will go far" or something like that. Then you will recieve skorms bow(i got it on my first try)

For the sentinus, its easier. If you're like me and like being purely good, make sure that if you were purely good you got skorms bow first to bring you closer to neutral. Then go to the Temple of Avo and donate around 60000-70000 gold and you will gain good points and the guy will say "the gods are pleased with your donation. very pleased" and you will get the sentinus.

Easy as pie.
