Nundu Bay (mission)

The mission start will have you in the middle of the encampment where you have to keep Elder Jonah alive. Attacks will alternate between the different entrances of the encampment. After killing 2 boss groups, a Harbinger will charge in. Use the vial of water skill given by the Elder on the Harbinger before attacking it as it won't take damage without it. After a while, it will stop taking damage so use the skill again. Be careful as these creatures can do massive damage and wipe out your party in seconds. A MM hero works good in this mission.

Keep killing the waves of normal enemies after this. After a while the second Harbinger will charge in. Kill it. Then one last wave of enemies will come to you. Kill them. At this time, go out towards the fort and basically follow the story line.

To get the bonus, you have to kill two Harbingers BUT not the Harbinger of Nightfall as that will end the mission. This bit is tricky. Clear enemies from outside the fort. Then go to each different entrance and lure the harbringers out. Kill the enemies surrounding them while keeping at least one hero with rebirth way back just in case as the Harbingers do massive damage.

Bonus will be done once you kill these two Harbingers. When done go to the main entrance and kill the Harbinger of Nightfall to end the mission.

Bosses

 * Priest Zein Zuu (Margonite): Spellbreaker


 * Scribe Wensai: Invoke Lightning


 * Commander Chutal: Anthem of Guidance


 * Zealot Sheoli: Arcane Zeal

Tip/Hint
Do not accept the Vial of Water skill when first offered. This will allow you to roam around and eliminate any (or all) groups of Margonites in the map, except for the Harbingers. Once you are satisfied you have a clear path back to the fort, go back and now accept the Vial of Water skill. This will trigger the normal mission, with the boss groups now advancing on Elder Jonah.
