Walkthrough
In order to complete the optional objectives in this quest, you will be required to obtain Charr Explosives. These can be obtained by killing Charr Firereigners. From where you start, head over the river to the East, to the most North-West red icon on your minimap.

To complete this optional task, you must complete all the other optional tasks. This will reduce the Garrison metre on your screen. This task shows on your minimap as the red icon to the North-West. It is 4 Charr carts. Simply drop a Charr Explosive beside one of the carts to complete this objective. Note: 1 explosive will destroy all 4 carts. There are 2 watchtowers, one to the North and one to the South. The watchtowers have a group of Charr that stand guard (do not move) and a patrolling group each. The patrolling group contains a Firereigner which will give you the explosives required to destroy the towers. Drop the explosives beside the towers to destroy them. There are 2 siege devourers. One to the North of the Northern watch tower, and the second to the South of the Southern watchtower. Both are guarded by a group of Charr, however the group of Charr guarding the Southern devourer contains a boss. For this objective, you must 'talk' to the devourer with the explosives in your hand. Dropping explosives beside them will not work! Simply talk to each devourer and they will fire the explosives toward the Charr camp.
 * Find Ways to weaken the Charr Garrison
 * Intercept the Charr Supply Caravan
 * Destroy the Watchtowers with Explosives
 * Employ the siege devourers to fire explosive charges at the garrison.

Head to the Charr Camp

At this point, your character should say something along the lines of 'lets go, there is nothing more we can do from here'. If not, you have missed something (check your Quest Log to ensure all optional objectives are complete). Once ready, head to the green marker on your map. There should be relatively few Charr left in the camp. Firstly kill the group of Charr hanging around the entrance. Then, head over to the left, and kill the group here. Now you should be left with just the 2 boss'.


 * Defeat Harvest Soulreign

Harvest Soulreign is a level 28 Necromancer boss with Spiteful Spirit. He is in a group with a level 28 warrior boss. Note: you do not have to kill the warrior boss. If Soulreign dies, the mission ends, irrespective of the warrior being alive or not. He is relatively simple to kill, easily done with Heroes and Henchmen. Once Soulreign dies, a cutscene begins and the quest is finished.
