About Savagery: I read somewhere else (I don’t remember where, sorry) that the skill is only applying its bonus damage to other certain skills when used. It is not applying to normal basic attacks, which is why he might call it a “fraud” skill, as the description would then be a little misleading.
Also - Can a Korean-savvy person translate the information about how and where he got the gems? I can see just from Google translate he is talking about specific areas and enemies, so I know the info is there. Google translate can only go so far though.
