does any1 know the walkthrough the curse q? or does this quest end in the act 1 or it continues in other acts?

Well he gives hints to where to look:
- the herbwoman
- Quarim (on the same map)
and if you've spoken to the vendor on the marketplace in hillbrand you would have had your last hint :).

i've spoken to the herbswoman to quarim i've gotten the wax puppet by force i've destroyed it ! smth else? cause nothing happens dude says he is feeling much worse

the vendor lady in city market told me about how she was looking for a finger or smth like that
but nothing happens

do i have to find that?

did any1 of u ppl finish this quest?

about finger or about raubsticht?

Well yes, the quest completes when you destroy the puppet and you speak to raubstich afterwards. (You get some exp and gold for completing)

From whom did you get the wax puppet and what do you mean by force? You should have had a dialog with Lotti where she confesses that she cursed raubstich. Afterwards she attacks you.

did that nothing happens
i destroyed the wax figure and still sick , can it be that i haven't judged the girl but i killed her and got the wax figure??

Yes, you must try to arrest Lotti to properly finish the quest. Talk to Raubsticht's assitant Quarim (NE from Raubsticht), and to Susane in the marketplace.

so if i killed her before arrest the quest cannot be ended?

Yep.

I'm on that quest and am stuck trying to figure out how to destroy the puppet... Is there an NPC to talk to, or should I try dropping it and force-attacking it?

Edit: /derp, I forgot about the "Destroy Item" button in the picture... is that the end of the quest?

I must have talked to these people out of sequence, because all characters involved have nothing else to talk to me about so I can't complete this quest. I don't remember pissing off any of them, except for maybe Lotti when I accused of her being lovers with so and so. Oh well, another unfinished quest.

Check your notes and your proofs.

Under your notes, are any of the following items listed there?

The herbwoman telling you to destroy a small figure symbolizing the bewitched person.

Quarim's suspicion that the curse on Raubsticht is due to him executing someone.

Belief that Raubsticht's curse is due to his execution of Hans Falkner and someone close to Hans cursed him.

You are ordered to arrest Lotti on reasonable suspicion of witchcraft.

Under your proofs, is the item there?

Probable that the person who cursed the executioner was Lotti Frankmuller because she was the lover of Hans Falkner who was executed by Raubsticht and the curse may be a revenge on the death of her former lover?
