Dialogue
 * "The ranks of the ice elementals which serve as Grenth's palace guard have been depleted by this latest attack by the Terrorwebs. I will call for the Ice King to summon a new defensive force. You are needed to protect the Ice King during his ritual, and to ensure that the Terrorwebs do not use this opportunity to strike at me once again."

Walkthrough
Once you accept this quest, Terrorweb Dryders will spawn nearby north-east of the Reaper's location. There are four waves, each wave will consist of six Terrorweb Dryders which will then immediately break up into two smaller groups of three each. One group will head towards the Ice King while the other heads toward the Reaper of the Ice Wastes.

You will have about 30 seconds to complete each wave of dryders, if you do not dispatch of them quickly the next wave will approach and you can quite easily be overwhelmed. Consider splitting the group up and having one half at the Ice King's spawn location ready to intercept incoming dryders while the other half triggers the quest and defends the Reaper.

The Ice King has four Level 28 Ice Elementals to assist, but they as well as the Ice King will fall quickly to the dryder's dangerous fire spells. Consider bringing Winter to convert the dryder's fire damage to cold damage, against which the Ice Elementals have a higher resistance.
