Ok couple of questions.ARROW of EXTRICATION can't find secret chamber...

With the Arrow of Extrication quest, you'll be in Bravil and go to the castle. Bribe a couple of guards until they give you some info about a southeastern tower. So go into the castle and go to the north wing and head left, pick the lock and you'll be in Aren's chambers. Directly across from you when you enter the chamber, you'll see columns in the wall. Activate the right one and it'll take you to the Wizard's Grotto. You'll go through dungeons upon dungeons and finally arrive at the tower. Head to the top, grab what's in the chest next to Aren.

Canvas the castle, you have to find THREE clues. You've found the paint on the rug in the dining hall and the lecturn. But in the West Tower you'll find, behind boxes, a painting. Go back and check the lecturn and it should open.

All you have to do for the Collector quest is find one statue, when I did it, I went with the easiest at the Ayleid ruin of Culotte because there's only four zombies and one small trap. Cake walk. Take it back to any city, it doesn't matter which because they'll find you anywhere. Sell it to a merchant and walk outside of the store and hit select and just wait for 24 hours. It'll take less than that but they have to travel to the city your in. You'll be approached by Jollring, the man servant of Mr. Umbacano. And the adventure begins.
