## What changed **Onslaught Mode beta** — coming to an end **Xbox availability** — The First Descendant is now available in additional countries and regions on Xbox Store, with Game Pass subscribers in new Xbox PC markets able to claim in-game benefits **New event** — "Esiemo's Dice Run" added **Battle Pass Week 12** — "Defense" Weekly Challenge will be replaced **Skill behavior while mounted** — standardized across all Descendants; toggle-type skills will end when mounting vehicles, and buff skills will no longer generate new stacks while mounted (affects **Bunny's Lightning Emission**, **Viessa's Ice Sphere**, and similar abilities) **Enemy elimination while mounted** — reduced efficiency from continuous eliminations while moving on vehicles to align with intended scope **Exterminator** — explosion effect improved **Recommended Party and Quick Join matchmaking** — rules improved ## Bug Fixes - **Axion Plains "Technical Research Institute"** — fixed interaction with interactive objects not completing while moving - **Infiltration Operation "Legion Laboratory"** — fixed Weak Point of Commander "Sculptor" sometimes not being destroyed - **Research Institute** — fixed search bar not resetting when switching Research tabs or exiting the screen ## Overall The First Descendant standardizes mounted skill behavior, adds a new event, expands to new regions, and fixes several gameplay and interface issues.
  • The beta period for Onslaught Mode is coming to an end.
  • The First Descendant will be available in additional countries and regions on the Xbox Store.
  • Additionally, Descendants playing on the newly added Xbox PC markets who are subscribed to Game Pass can claim in-game benefits through the in-game shop.
  • Added the new event "Esiemo’s Dice Run".
  • The Battle Pass Week 12 Weekly Challenge "Defense" will be replaced.
  • Currently, when a toggle-type skill is active and the player mounts a vehicle, skill casting ends. The baseline for buff skills that grant status effects over a duration was to maintain those effects when mounting a vehicle.
  • However, while it was intended for buffs with granted status effects to remain active upon mounting (e.g., Bunny's ‘Lightning Emission’ skill), having new stacks of those buffs added while on a vehicle was not in line with our baseline.
  • In Viessa's case, continuing to attack while mounted after "Ice Sphere" has already been applied was considered normal behavior. However, we have determined that new "Ice Sphere" instances being generated again while on a vehicle is inconsistent with our baseline.
  • This situation had existed previously, but we have confirmed that simply moving while mounted allows players to continuously eliminate surrounding enemies, resulting in efficiency beyond our intended scope. We plan to address the related behavior to align it with our baseline. Going forward, skill behavior while mounted will be applied under the same consistent standard.
  • Improved the explosion effect that occurs when using "Exterminator".
  • The Recommended Party and Quick Join matchmaking rules have been improved as follows.
  • Fixed an issue where interaction with interactive objects was not being completed while moving during the Axion Plains "Technical Research Institute" Mission.
  • Fixed an issue where the Weak Point of the Commander "Sculptor" in the Infiltration Operation "Legion Laboratory" would sometimes not be destroyed.
  • Fixed an issue where the search bar would not reset when switching Research tabs or exiting the Research screen in the Research Institute.
