I've already talked about the other two rare types that can be found on Isle of Thunder, the "normal" rare, which spawn at regular intervals, and the rare ones that can be summoned with Shan'ze Ritual Stones. This is the third type of rare from the Isle of Thunder that can be summoned through scrolls that can be collected from all enemies on the island, including quest chests (Arcane Treasure and Sunreaver Cache) and treasures from the treasure hunt scenario (Lei Shen's Funeral Treasure, Thunder King's Treasure, Mogu Chest and Golden Chest).
Achievements are linked to the 3 bosses:
- kill 1 of the bosses: all mogu are in the wild
- kill the 3 bosses: The people of Mogudor
Haqin of the Hundred Spears
This boss can be summoned with Haqin's Incantation Scroll in the Courtyard of Bones, just behind the Kirin Tor quest giver (38.9, 59.3). He has a little less than 4M health points (3 939 410).
This boss can be summoned with the Vu's Incantation Scroll in the Court of Bones. His place of incantation is in the center of the square of stelae, near a large tomb (38.5, 54.8). He has a little more than 3M health points (3).
Master Forge Deng
This boss can be summoned with Deng's Incantation Scroll in the Courtyard of Bones, in the cemetery on the left (38.7, 58.1). He has almost 4M hit points (3 939 410).

/ way 38.5, 54.8 Seen
/way 38.9, 59.3 Haqin
All these bosses can be killed by 1 single character although it is better to invite 1 friend because the scroll is lost in case of failure. Feel free to post your screenshots of you facing these bosses!
