(This post contains minor SPOILERS for Chapter 1)

After searching GOG and several other forums, I've found that I'm not alone in this problem.

Prior to accepting the Kayran: Osmurk quest (i.e. prior to finding the wreckage), I had already done a bit of exploring of the forest and fought my way through the waterfall, where I picked up osmurk.

Then I went to the wreckage, where the quest prompted me to find osmurk. My osmurk has vanished from my inventory. Back at the waterfall, I can no longer retrieve a "new" osmurk from the blue-colored rock. No retrieval prompt comes up.

So unless I am missing something, there's no way to get the osmurk. Thus this portion of the quest is broken if you picked up osmurk early. There was no way to know this would happen. I figured it'd stay in my inventory, even if it was for a future quest (at the time). But unfortunately, it instead simply vanished when the quest to find it came up.

Does anyone know whether this is something that might be fixed in a patch, or should I try to fight the Kayran without it (that sounds sucky)? I'm definitely not re-loading to before I explored the cave; way too far back.

Thoughts?

Thanks.

I'm pretty sure you can create mongoose without the ostmurk.

Also, it doesn't hurt to fight the Kayran without the Ostmurk. Just don't stand directly in front of it.

I was surprised to find that I didn't need it at all. Even a little.

Doesn't the quest tell you to either collect the ostmurk or get (buy) it from Cedric (or one of the other merchants)?

The problem is not that you picked up the Osmurk early. The problem is simply that there is only 1 Osmurk in the game. - and you either sold or used yours.

I've been through this Act a couple of times and always grab the Osmurk before I get the Diagram for the Mongoose potion from Triss... then I make the potion using another ingredient - keeping my Osmurk. (Why? Just 'cause I can, I guess).

If there was a way of sending you my extra Osmurk by email, I'd help ya out!


[edit] - there's a mod to get it from a vendor. Check the first links here for MODs.

Yes, you can use any ingredient that contains fulgur. If you've done the endrega contract you should have a big heap of endrega embryos that will do a substitute, just be careful not to use up the valuable Queen endrega pheromones.

Yes, but you have to have to Osmurk in inventory to "pass" the quest to find it. I think that's what the OP's issue really is.

It looked like the quest was working fine for me, but it's still open.

I got the quest, spoke with Cedric and was told where to find the cave. I then immediately tried to see if I could brew the potion without the Ostmurk, and was successful. I was then told via quest update to go meet Sile.

The Kayran: Osturk quest wasn't marked as completed.

Slightly stale thread. But anyway, that quest doesn't get marked as complete until you drink the potion and kill the Kayran, if memory serves.

I can confirm this. The ostmurk quest is only marked as completed once the Kayran is killed.

Awesome, thanks guys. Re stale thread, yeah, I'm behind on my TW2 first playthrough. :P

NO, it says find it yourself or ask Cedric for help. Finding it earlier may have alchemy consume it when brewing other potions but the Mongoose potion can be made with other stuff indeed and as it was said, only after the beast is dead it will be marked as completed.
