could you please add some of the required mobs? there are very few to do the quest properly. Please make sure they are not too close to each other, otherwise they chain aggro :)
Fixed. There were fewer Eternal Guards than it looked: two of them were stuck in the ground under the island and could not be reached. They are back on the surface, and we added two more Guards, two Eternal Swordfighters and one Eternal Priest on their retail positions. Each new one stands at least 16 metres from any other monster, so you can pull them one at a time. There are now 8 Swordfighters, 7 Guards and 6 Priests around the Grave of Steel. Live after the next server update.
