The first is dropped by Lavascale, the 2nd by The Stasis Preserver (yellow con, Dreadfang spire), the last by Enforcer Husrag in Stormkeep (red con).
The Skullcage is clearly not on the same foot as the barbute.
It seems to me that the Lavarock Skullcage's AC should be brought to 30 to make it desireable for the tank classes, since it's designed for them. Maybe then it would be overpowered, so possibly down the sta to 12?
