A bit more information.
Here’s Plague Doctor’s skills and attributes, no videos but just screencaps. Taken from the KR Tester Forums.
Also, a bit of interesting information. Shinobi might be available but as a hidden class.
However, it’s unconfirmed as I’ve not seen any actual Shinobis nor have I seen any evidence of people being a Shinobi so far. Take this with a pinch of salt until more evidence and information comes to light!
The item says ‘Disposable Vial/Reagent’ and the description ‘Disposable vials used for Shinobi hidden ban(class or quest?).’ This is a chest at that location in Vieta Gorge.
The post also mentions where it’s found but no confirmed mention of actually being able to get Shinobi. You find this in a treasure chest in the location there.
People comment that you still need to be Swordsman to be a Shinobi.
[For any interested, here’s the post’s raw text.] (http://pastebin.com/c53js1Eg)
EDIT: There seems to be two more items, with people saying there might be a fourth one.
I don’t know where to get the plant or yellow bottle item, but I did pick up the Disposable vial item, it’s in Vieta Gorge at the location of the first screenshot.
