Ward Up
“Five voidsent demons have descended into the Singing Shards, devouring the souls of any and all who cross their path. Early attempts at slaying the creatures have all ended in failure, for as long as one survives, it will continuously summon the fallen back to its side.
If a party were able to somehow time the killing blows necessary to fell all five of the creatures at once, victory may be possible. However, the demons will try and stop this by employing a combination of complex battle formations to thwart their pursuers' plans.— In-game description

Strategy
In Ward Up, players face 5 flying demon-like monsters called Camio. They all have cleave attacks and point blank AoE attacks. Try not to stand in front of them and avoid the AoEs.
These Demons have 3 formations. In the initial formation, one of the 5 demons have invulnerable. In the second formation their damage is increased. In the 3rd formation they spawn a giant gargoyle. When their HP is low and they spawn the gargoyle, be sure to kill the gargoyle first.
The tricky thing about this fight is all 5 of the flying demons have to die around the same time. The window of time is around 20 to 30 seconds between the first death and the last death. If players do not kill them at the same time, the demons that are alive will resurrect their dead companions.
Players must use coordination, AoE attacks and shifting their damage to complete this guildhest. Avoid using damage over time (DOT) attacks if the demons are not dying at the correct time.
- All the demons MUST die around the same time. Coordinate yourselves and your damage output.
