完美胜利

Players must split up into three teams before the meta begins. Each of the teams will stand on a disc to pledge allegiance to a legion - pledging to one legion is irreversible for the current meta, and will prevent you from joining a different legion's trial. Speak to the charr at each disc to enter the respective legion's arena trials. Mounts are disabled within the arena. Blood - First challenge Stand on the capture points and keep ooze out until all three are captured. Three elite ooze coloured red, blue and green will spawn - stand in the respective toxin clouds to gain a toxin effect to kill them. Iron - First challenge Fight the ooze as they appear. Occasionally the ground will be marked in five separate places; all five must be stood on simultaneously without foes entering the rings to progress. Eventually more ooze will be forced to the surface. Defeating Ash - First challenge Pick up an empty barrel, and sneak across the room using the bundle abilities to the leak sites. All - Second challenge After completion of each of the first challenges, an Elite ooze will appear in each arena. Kill it. All If the challenges time out, or if all challenges are successful, then the walls of the arena will sink into the ground such that everyone can join each other. At this point, if not all legions completed their challenges within the time limit (e.g. one lane failed), then a random Elite Ooze event will spawn as a consolation prize. No Blood Legion Key will be awarded. Otherwise, a Champion Prismatic Ooze will appear and the main event will start. Stand on air vents when prompted. Avoid Toxic Ooze roaming around the arena or destroy their breakbar to kill them. Use the Red/Green/Blue toxin clouds to penetrate the invulnerability effect when prompted. The Champion Ooze will split into three Elite Ooze at 50%.

The achievement will not be granted if you arrived at the event late. es:Pruebas de la Fosa de Légamos fr:Épreuves de la Fosse à limons
