this one https://u.eq2wire.com/item/index/778463038 If it matters, my copy of the rune came from quest started by raid-trash drop in Raj'dur Plateau: The Hunt. The effect that it's supposed to provide does not register in GuildHall or in Raj'Dur Plateau. When mousing over the rune in an equipped charm, it says "Focus Defense 0/1" - meaning it's not registering this rune as qualified to provide this effect. It is then also no surprise that the 346.1 crit-bonus that should be granted by this effect is not adding to my stats
I also have this as a drop from an instance and noticed it is not working now that you mention it, as well.
I just checked and by contrast, the VoV Focus Defense adorn that came from Merchant's Den is working just fine in RoR solo zones, so this appears to be an issue just with the new one.
