I'm not Kiya or Raze <smile> so I use words not screenshots or links.
Entering the forest, head south (not east) and you will find it at the bottem of one of those dead-end areas. If you are deep in the forest head back over the series of little metal bridges. After the last of them you aren't far from the alchemist but don't go to him - head left (just curve around the water and head south to the bottem and there it is).
