I´ve got a few questions cause I am stuck into act 3, here they go.....

1) I´ve made throught the Corin´s Quest and now I´ve to talk with her undead friend Kathrin, I´ve got the undead´s necklage, the book Libre Necronomicon and I´ve found the tomb where she is buried....... I need to take her testimony but I don´t know how to do it.

2) I don´t know how to take the testimony of the grave robber Vick Lenght. Do I need some kind of evidence instead the other grave robber´s testimony? The torture is not working on him......

3) I´ve obtained the Gardener´s testimony after torture him and I don´t see the way to get forward into the King´s murder quest..... He seems to be one of the Cult´s members and speaks about a place in the Gardens of Grief but I can´t find it.

4) Thinthan´s oil....... Where is it?

5) I´ve killed a crazy paladin that atacked me and when I´ve reached the citadel and have spoken to the paladin´s commander, he refuses speaking because the "killing incident". Was this quest important? or is the commander´s dialog important?

Thanks in advance for your reply......

1. You have to talk to the friendly priest first, then equip the amulet and go the grave.
2. Vick doesn't feel pain so you can't extort a confession out of him. There's an open grave in the graveyard district, clicking on it will give you a new dialogue option with a bandit in South-East Alvaron.
3. The ritual site is in the middle of the gardens of grief, in a bush. But to progress the main quest you have to continue with Corin's.
4. It's the bottom level of the church dungeon, you can't get to it yet.
5. The paladin commander on the first floor of the citadel will want his amulet. Another one in the Citadel surrounding wants his sword, but these are unimportant sidequests.

1. Who is the "friendly priest"?
2. The other bandit is who says Vick is one of the other persons who rob graveyards. There is no way to obtain Vick´s confession?
