Artifact Gate

An artifact gate is the location where an artifact is spawned if the player completes the task to unlock the artifact. Some of these tasks can be done by every class with no items (e.g. on Sunken Tomb, you can just drop down), but some of these tasks require special classes or even items (e.g on Sky Meadow, you have to crack up the ground, this can't be done by the Commando).

The name of this structure is given to it by the community (we need someone to look up the data to confirm this name or get the real name).
