Sorry but this won't happen. The Court Minstrel helmet is a class specific item. Faerune for helms is only available on the archetype helms from T6/T8 and a few random all/all helms here and there.
Somehow I fail to see the reasoning behind this. Every helm available in VP has Faerune II including the Aged Crown of Rile from PD.
Jump to T7 and you instantly have the Gem Encrusted Crown from the very first boss having Faerune II.
As for T8, every level of the HoH evolving helms for every class has Faerune II including every helm from Nadox.
If you look at the mods you have on the Crown of the Court Minstrel, as Beat said, Dark Thunder is basically useless for a bard and also available on the gloves. The cleave X is available on every pair of pants leaving an average item that is only useful for the clicky since wearing the Nadox helm or the HoH helm is far more useful since they both have the Faerune II. Anyone that has these options available to them (And they should since the Court Crown comes from the 3rd? boss in nadox) would be better off using them and just picking the crown out of their bag for the clicky letting you still able to stack the Gladiator and having the Faerune II.
Thanks
