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 or by using the Ammo Cart near the Supply Caravan. 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. Doing so will reduce the Garrison meter on your screen.
 * OPTIONAL: Find Ways to weaken the Charr Garrison


 * Intercept the Charr Supply Caravan
 * This task shows on your minimap as the red icon to the North-West. It is four Charr carts. Simply drop a Charr Explosive beside one of the carts to complete this objective. Note: One explosive will destroy all four carts. An Ammo Cart sits nearby and can't be destroyed (unless you don't use another explosive on it), it does however supply additional Charr Explosives on use.


 * Destroy the Watchtowers with Explosives
 * There are two 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.


 * Employ the siege devourers to fire explosive charges at the garrison.
 * There are two 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.

At this point, your character should say 'That's as much as we can do from out here. Let's make our way to the camp'. If not, you have missed something (check your Quest Log to ensure all optional objectives are complete). Once ready, head to the quest marker on your map. There should be relatively few Charr left in the camp. First, 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 two bosses.
 * Head to the Charr Camp

Harvest Soulreign is a level 24 Necromancer boss with Spiteful Spirit. He is in a group with Gordam Griefgiver, a level 24 Warrior boss. Note: You do not have to kill the warrior boss. If Soulreign dies, the mission ends, whether the warrior is alive or not. He is relatively simple to kill, easily done with heroes and henchmen. Once Soulreign dies, a cutscene begins and the mission is finished.
 * Defeat Harvest Soulreign

Hard Mode

 * You do not need to do the optional tasks of killing the Charr guarding the watchtowers or the ones guarding the siege devourers. You only need to drop the explosive charges near the watchtowers or touch the devourers while holding them. A good way to do so would be to use one character which will run alone, blitz in and hurry back out.


 * Once the mission is activated, a fairly large group of Charr, consisting of Seekers, a Dominator, Hexreaper (and maybe others) run in ready to attack. However, you can immediately run south and a bit east out of range, they don't chase in after you. Then, if you have a minion master, there are some Skale you can easily take out to get minions and will have time to organize and put on enchantments or buffs (such as Signet of Strength or "I Am The Strongest!"). You might even be able to avoid them altogether.


 * If you are going for Vanquisher title, and don't have Plan A activated, you will end the mission left in the garrison free of enemies there, thus making vanquishing a bit easier. There is a shrine just to the west you can get to without having to fight any enemies. Equip lots of hex removal skills, as the hex spells are quite brutal.
