Void Fields

The Void Fields are a Hidden Realm accessible only through the Bazaar Between Time. It is a necessary location for the challenge ...To Be Left Alone, which unlocks the character Acrid.

The Void Fields can only be accessed via the Null Portal located in the hidden cave in the shaft underneath the Blue Portal in the Bazaar, with the Null Portal only being accessible once per run.

Until the cell is stabilized, the Void Fields will constantly "suffocate" the player for a small percentage of their health. This suffocation effect can kill the player.

Stabilizing the Cell
To complete this Hidden Realm, players must activate and survive nine separate cell events. Each cell event will result in either a new type of enemy or a new item's effects being given to the current enemies. The first two given items will be Common items, the next two will be Uncommon, and the last will be a Legendary. By the end of the event, there will be four different enemy types with five items.

Upon each cell event's completion, the players will each be granted an item. The first four events grant Common items, then the subsequent four grant Uncommon items, and the final will grant a Legendary item. The rewards are not tied to the items given to the enemies.

Logbook Entry
The Environment Log can be found below the starting area, on a ledge with part of a large ring on it. As noted in the tips below, the log disappears after 5 minutes pass.

Tips

 * Enemies given Common or Uncommon item effects have properties equating to small stacks of the given item.
 * Generally, it is a stack of five for Common items, and three for Uncommon items.
 * and, to a lesser standpoint, both and the  can all be used to entirely negate the suffocation effect.
 * On-damage items such as are triggered by the suffocation effect as well.
 * Barrier does not take damage from the suffocating effect. It's unclear whether this is a bug or intentional.
 * The Null Portal to exit the Void Fields is always available, so if players are unsure of their survival, they may exit at any given time. Do keep in mind however, that the Null Portal in the Bazaar is only accessible once per run- regardless of if the challenge was completed or not.
 * The Environment Log disappears after 5 minutes pass.
 * After a cell is charged, the next cell's location can be found by following the beacon of light it emits.
 * If the Artifact of Kin is active, no additional Monsters are added past the first cell event. This greatly reduce the Void Fields' difficulty, especially depending on who the only Monster is.
 * If using the Artifact of Sacrifice, with enough skill or a strong enough build, items can be farmed here indefinitely, due to the high volume of enemies and the stopped timer. This comes at some risk however, due to the monsters having items, and the suffocation effect slowly ticking health down if not mitigated.
