I have found three idols to include the one in the woods, I'm running all over the place trying to find last two. Any ideas where they might be.

As i remember it, Lysandra the Vampiress in the Dungeons/Sewers has one, then above her, there is a room with a leaver, that lets you access D'Solto's tower, where one more is..... Also one in the Armory, and another in the castle treasury.....

You need to collect five idols. The first idol is from killing the skeleton watchman in the lacksmith area. Another is from pulling all eight gargoyle switches properly. The third is from Ardibren - after talking to him meet him outside. The fourth is from D'Soto's room. The fifth is from the vampire mistress (try to steal it just to see what she says).
