After opening the Hydraulic Door, I found myself with extra Wyvern Stinger (or Wyvern Poison bottles).
I know I don't need them to finish the game, but two things piqued my curiousity:

1) The Stingers\Poison have a price tag, yet, I cannot sell it to anyone.
Is there a merchant who will accept it?

2) According to the Poison bottle description, it can be used to create "Delay Poison Potion" or to Anoint a weapon with the Posion.
how do I do that?

Anyone out there knows the answer? :hmm:

Update:
...five days passed...
So far, no one tried to pull the sword out of the stone.
I suppose that is because the items have NO real use except for the hydraulic door. :mad:

Was it too difficult to write on the bottles "Poison that can contaminate water supply", and have it's price labeled as 0 (like many other items)? :(

I think that with a high enough alchemy skill, u can create potions in the lizard dungeon with the altar. In the library / laboratory...

I'm not sure tho - never did it myself.

Yup no use for them. Unless you want to use the stingers as short swords ...

Well, too bad, it would have been nice to improve any weapon with a venom effect.
Using the stingers as a short sword is possible, but at this part of the game you can get much better weapons.

If no one else manage to find a solution, I guess there is nothing more to add.
Unless, someone is ready to take the challenge of enabling the use of the potions and the stinger (that's right, reprogram the whole thing).

Good Fortune, ;)
