Dungeons

Dungeons can drop from various enemies in the world. They appear as Avian aircraft carriers which take a few seconds to appear. Once they have stopped moving, you may enter the dungeon at any time within a 30-second interval by flying into the carrier's tower --- once this time has elapsed, the carrier warps away, presumably to the appropriate dungeon.

Like world bosses and quest enemies, dungeon entrances modify the "Rally to me!" emote while the player is nearby, causing the message "At !" to display instead of the usual message "Rally to me!"

Dungeon drop rates are calculated per player. Therefore, if 8 people hit an enemy, the chance for a dungeon drop is 8 times as great.

Leveling Dungeons
Leveling dungeons, dropped from low-level squad leaders and world bosses, offer superior equipment compared to the zones in which their entrances appear. Though equipment items obtained enemies and Treasures tend to drop at the dungeon's tier, those obtained from bosses and Big Treasures (when the damage threshold is met) tend to drop at 2 tiers above the dungeon tier.
