Justicebringer 3000 Specs

Source
This item requires Engineering 350 to equip but 375 to learn and is learnt from dropped in Sunwell Plateau. The Schematic is currently not listed as BoP but is only usable by Paladins.

Speculation
Although not officially listed as BoP, it is entirely consistent with current game mechanics that only Paladins with 375 Engineering will be able to get this drop.
