Command

The Artifact of Command is an Artifact that can be found in the Hive Cluster level. If the artifact is generated, it will appear in the top right area. In that area, there are several pink ropes that flicker; the character must jump from rope to rope to collect the artifact. Alternatively, a player with a Photon Jetpack can simply fly up and grab the red vine directly beneath the platform, which doesn't disappear. Or even easier with the use of a Huntress while jumping and using her teleportation ability.

Chests


The artifact causes random items to become 'chests', which are outlined either, , , or. Please note that you still need to purchase regular chests, which will drop these choice chests. Which items are in the chest depend on what color the outline is, a white outline would give such as the War-banner, Monster Tooth, and Rusty Knife for example.

Note that you can choose any item from the chest's rarity, regardless of whether or not you've unlocked it. You can't, however, get a from a  chest. To select an item, move over a chest, press your interaction key, navigate the menu with your movement keys, and select the item with the interaction key. Beware selecting items dropped by an existing shrine, as this will cause you to purchase the shrine again as you select the item. There is no way to prematurely exit the menu, so selecting an item leaves you at the mercy of monsters who are nearby.

While selecting items:
 * You can use any actions that can be done on a rope (e.g. jumping, using a Use item, certain abilities).
 * For any other actions, it seems that if the buttons are held down when starting the selection process, those buttons are considered held down. For example, basic attacks still seem to spam.

Bugs
It is still possible to acquire boss items, such as Ifrit's Horn and Nematocyst Nozzle. Other item drops are unconfirmed.

Using the Captain's Brooch and Skeleton Key in Co-op may cause you to no longer be able to open anything, including these boxes. If this bug occurs it will be fixed by going to the next level but will trigger again as soon as one of these items are used, thus, for the entire duration of the game session. There is no known way to predict if the bug will happen, but seems unlikely to be triggered by the host player.

If two players activate the same chest, one player (usually the host) will be unable to move or use skills, though they can still jump and activate use items.
