What this guide applies to
This guide records the official May 2026 Version 2.4.1 announcement. It explains systems named in that update, not a permanent event calendar, a guaranteed drop route, or a ranking of the best Morphed Deviation.
Gravity Abyss activities
Gravity Imbalance regions
The official announcement says Gravity Imbalance can affect selected Stronghold regions during the Vision. The affected locations are marked through map pins. Exploring them can provide Mods, Gravity Crystals, and other rewards.
Riftwalker Relics
Riftwalker Relics are marked on the map. The update says that approaching one summons elite enemies and causes the relic to ascend; defeating those enemies stops the ascent. Its listed possible rewards include Mods, Morphed Deviations, and Abyssal Cores.
Aerial Hunt
According to the announcement, the Riftwalker appears above three random Settlements fifteen minutes after the Vision begins. Players can enter the platform through a summoned portal or teleport with map pins. The precise timing, locations, and rewards should be checked live because event rules can change.
Abyssal Cores and rewards
The official update identifies Abyssal Cores as a reward that can come from Riftwalker Relics and Aerial Hunt. It lists Epic, Legendary, and Mythic rarity tiers, and says their possible rewards can include Shiny Mods, Abyssal Essence, and high-level Morphed Deviations. This is not a drop-rate promise.
Morphed Deviations and mods
Version 2.4.1 announced three new Morphed Deviations: Digby Boy - Gravity Abyss, Atomic Lighter - Gravity Abyss, and Zapamander - Gravity Abyss. It also announced the Aero suffix Mod and the return of the Downstar Mod. The announcement describes Aero as usable in aerial states, including jumping; evaluate the current tooltip before making a build decision.
Before you enter Gravity Abyss
- Confirm that your server has the Visional tag and the Gravity Abyss Vision is active.

- Read the current reward and Mod tooltips before spending Gravity Crystals or changing a build.
- Do not treat an older route, core rarity, or Morphed Deviation recommendation as current without a matching patch and scenario.
