The Crag Field is a rocky biome dominated by large geological formations.


The Crag Field is situated between the Grand Reef, the Crash Zone, Kelp Forest, and shares its border with one of the Grassy Plateaus. To the south of the Crag Field is the Crater Edge, and to the north of the Aurora's engines. This deep biome features large rock spikes and rippling stone hills, bearing resemblance to the older Grand Reef, all of which is formed atop a massive crag dropping down into the aforementioned biome.

The Crag Field is a resource-rich biome with some low-level predators. Groups of Bonesharks are frequent in the area, along with the occasional Mesmer passing by. Tiger Plants can also be found in this biome, camouflaged, and mostly hidden in the grasses within the rock structures. The biome also features a great abundance of minerals, both in node and deposit form, and other resources.

A few pods of Reefback Leviathans can be seen drifting in the water above the Crag Field.
