Wiki or game incorrect?

[Doktoor]

The wiki says that Gindlin Toxfodder in WK sells Delphinum and Thorny Ergot as poison supplies, but he's only got vials and whatnot.

How do you know which is correct and which isnt?

[Fammaden]

The game is wrong, buy them from the wiki instead.

[BlackBellamy]

The game is always wrong.
