Son of Hakkar can be found in Zul'Gurub.
These creatures are the key to defeating Hakkar. After death, the Sons of Hakkar leave a cloud of venom behind, which infects each player in range with a DoT that ticks every 3 seconds for 100 points of nature damage. Usually the venom will be cleansed, but when fighting Hakkar it is essential to keep the DoT and not to cleanse it. The Sons of Hakkar have approximately 15465 HP. Hakkar casts a life drain every 90 seconds, but if enough players are infected with the venom when Hakkar drains, he will damage himself instead of healing.
Sons of Hakkar were once famous for changing between three colors when tamed (yellow, red, and green) but are now permanently red.
