Actually two pieces.
The first was found out independently by several members of Maintankadin. The quest Burn Victims is best solved by throwing an occasional Holy Radiance while doing the other quest.
The second concerns the quest Solar Core Destruction. For some reason the clicky can be done while bubbled. As you can't take any damage while bubbled you won't get interrupted. Before the bubble drops (and you get a horde of angry flame druids crawling all over you) you'll get thrown to the pillar.
