This post is regarding the Dievdirbys attribute “Dievdirbys: Plant-type damage”.
The description says that you deal 10% extra damage (per level) to plant-type monsters when using a blunt-type weapon. After extensive testing this doesn’t work for magical attacks, however the skill description makes no mention of it being physical only.
I hope that you can check this out, as Dievdirbys is an extremely broken class right now.
