I found to day on a abdomination of missery an "Flawless magnaar stone". its states is a for a weapon socket, it does extra damage nature 125-165 ad a change of 10%.

But when in stalling it in a triple socketed mace which is empty I get the error can't be installed benefits are not allowed to stack?

What i'm i here dealing with? a bug or a historical arifact, this is the first use i do of it. if its an artifact can some one give the whole history.

thanks
