Walkthrough
To successfully finish this quest with only Heroes and Henchmen, it is advisable to have the following: Monk, Elementalist and Necromancer (Heroes); Warrior, Mesmer, Elementalist and Paragon (Henchmen). If your character is not a Monk, replace one of the Henchmen - that already matches your character - with a healer. When the quest begins you have 3 groups of margonites all coming toward you and your allies. One from left side (#1) and two from the right side (#2, #3). Attack the left side group first (#1) and its subsequent spawning groups (#4 and then #5). After that, it's tricky. Your party will have to deal with 15-16 margonites (#2, #3) on the quest starting point. They are all linked. You have to kill the healers fast (double Meteor Shower is pretty useful). When you lose 4 members of your team, retreat and ressurect them. Keep killing them until a new group (#6) spawns on the right side. Don't kill all the margonites from group #2 and #3 or else you're going to make group #7 spawn (leave the executioners for last). Keep spawning separately. Kill group #6 without killing the last of group #2 and kill every single group that spawns. At the end, the Margonite Seer comes in from the left side (accompanied with yet another group). Kill them to finish the quest. Hint: Keep few Candy Canes in your bag, that can help.

Note

 * "They're on Fire!" (Paragon) and Searing Flames (Elementalist) will reduce all of the damage received by party to a minimum, having "Incoming!" as the paragon’s elite also helps to reduce damage even more.
 * While minions are not that effective damage-wise against margonites, they are very useful at soaking up damage caused by the Margonite Reapers' Mystic Twister, extra targets means that there is less likely of a chance that the spell will hit you. They also serve to hold the attention of Margonite Executioners while you are focussing on the Clerics.
 * Due to the large number of enemies, Lightbringer's Gaze is a very good mass interruption as well as AoE damage spell. Make sure you bring it if you have it, and use it early and often.
