In Maradino' cave there is a garden. At the back one can dig out the Key to the Study. There is also showel included

BUT...
There is a plant (easy to kill... too easy...) during the fight it spawns small plants around in the dirt holes with the *Click* sound. I have send my wizard with 110% poison res there and waited till all plans are spawned. Rest of the team was out of fight. There were 4 clicks but NOTHING happend.
Does anybody knows what they do???
