1 - Enter the room
2 - Let Gunga try to clear the room on his own
3 - CC the mobs (Ottos, mass hold etc.)
4 - Res Gunga
5 - Let Gunga kill the mobs
6 - CC Gunga (Wild mage belt)
7 - Move to the next room
8 - repeat (if 6 worked, 2 and 4 might not be needed)
Although isn't that Plan A with any quest we go in with Gunga? Guild policy I believe?
