The Fourth Warrior - Jhal'Dolek

Juna asks you to heat the leather cloak using Jhal'Dolek, you must apply a paste on the cloak while he lives to soak in the heat, then while the cloak is on fire you must soak it in his blood. To start go to Steamfont Mountains. In the geyser area (the one with the steam elementals and the harpies) there is fire salt you can mine. Upon mining this stand on top of a steam vent and use the salt to "seed" the vent, summoning the air elemental Jhal'Dolek Level 70 ^^ heroic. When he is summoned used the paste that Juna gave you in your back pack to keep the cloak on fire (warning if you die and have used the paste you will need to go get another paste as the cloak being on fire is a buff and goes when you die). When he dies he will drop a small chest with a heart, it is tradeable and has unlimited charges if more people need it. Use the heart on the cloak and return to Juna to complete.
