Walkthrough

 * The Great Destroyer is easily soloed with 3 touch ranger heroes, 2 henchmen monks, and an interrupt skill for Call of Destruction.
 * The quest takes place in a separate explorable area reached by talking to High Priest Alkar.
 * Clear the lava pool of at least the stationary Destroyers of Life in the direct path to the Great Destroyer. It is not necessary to kill all of them.
 * Stand on the hardened lava crusts, but beware that the Great Destroyer will convert them to lava using Lava Ground. Eventually there will be no safe area in the room.
 * The Great Destroyer will summon a random group of 3-5 destroyers using Call of Destruction. Be sure to interrupt this skill, and brace immediately for Enraged Blast.
 * Pain Inverter causes him to lose about 50% of his health after using Enraged Blast.
 * Consider also interrupting Lava Wave as it is the Great Destroyer's only healing skill. Otherwise, switch to life stealing or health degeneration while the Great Destroyer is submerged.
 * Ward of Stability can help immensely against the repeated knockdown of Lava Blast.
 * Consider bringing skills such as Frigid Armor or Avatar of Melandru that negate burning
 * Party-wide condition removal by skills such as Extinguish, Cautery Signet and Martyr are only a drain on energy because burning is reapplied every 3 seconds in lava. Instead, bring Light of Deliverance and spam it to heal through the burning.
 * Recovery and Recuperation help reduce the threat of burning to nearly nothing.
