Greetings, Descendants.

Here are the major issues that were found for The First Descendant in October.

We will continue to update this notice with any newly identified issues and bugs, as well as previously reported major issues. Please keep track of the updates during your gameplay.

[October 29^th]

■ (#8) An issue where the content of the “Battlefield Monster Hunter” Challenge Event does not match the Transcendent Weapon Acquisition Boost Target content

- We have identified an issue where the content set for the “Battlefield Monster Hunter” Challenge Event does not match the Transcendent Weapon Acquisition Chance Boost Target content.

ㄴ Normally, when the Transcendent Weapon Acquisition Chance Boost Target content changes, the same change should also apply to the target content of the “Battlefield Monster Hunter” Challenge Event.

- The Transcendent Weapon Acquisition Chance Boost is being applied correctly to the missions displayed in the “Content with ongoing events” section in the bottom-left corner of the map.

- In addition, please note that event rewards are being granted correctly when you clear the content designated for the “Battlefield Monster Hunter” Challenge Event.

- This issue is scheduled to be fixed in the 1.4.8 patch.

[October 23^rd]

■ (#8)(Resolved) An issue where the Beginner’s Guide quests are not activated

- We have identified an issue where the Beginner’s Guide quests are not activated and cannot be progressed.

- This issue is scheduled to be fixed in the 1.4.7 patch.

[October 22^nd]

■ (#6)(Resolved) An issue where some missions in Onslaught Stage 4 cannot be cleared because their completion conditions change while in progress

- Entry to Onslaught Stage 4 will be temporarily restricted until this issue is fixed.

- We are currently investigating the cause of this issue and will fix it as soon as possible.

■ (#4) An issue where part of the skill descriptions is not displayed in languages other than Korean when Freyna/Ultimate Freyna’s Transcendent Module “Neurotoxin Synthesis” is equipped

- We have identified an issue where the following text is not displayed in the “Venom Veil” skill description.

ㄴ “Enemies that touch the Toxic Haze are inflicted with Room 0 Trauma.”

- We have identified an issue where the bolded text below is not displayed in the “Putrid Venom” skill description.

ㄴ “Enemies inflicted with Deterioration or Hypersensitivity have decreased Movement Speed and take increased damage from the Unique Weapon.”

- We have identified an issue where the following text is not displayed in the “Venom Baptism” skill description.

[October 16^th]

■ (#4)(Resolved) An issue where the portal disappears when one player enters the Colossus Stage while playing the “Trials: Protocol 001” mission with two or more players

- We have identified an issue where, when playing the “Trials: Protocol 001” mission with two or more players, the other party members are unable to enter the Colossus Stage once one player has entered it.

[October 15^th]

■ (#4)(Resolved) An issue where World Completion rewards and Personal Contribution completion status are displayed abnormally in the Assemble Event UI

- We have identified an issue where rewards that have already been claimed in World Completion are incorrectly displayed as unclaimed.

- We have identified an issue where the Personal Contribution completion status is displayed as reset.

- Please note that this issue only affects the UI display, and reward items cannot actually be claimed more than once.

■ (#4)(Resolved) An issue where the “Toxic Skill Power Increase” from the “Ambush Setup” effect of the Trigger Module “Prepping in the Dark” is not reflected in the “Toxic Skill Power Boost Ratio” stat on the Descendant Info screen

- Please note that the “Toxic Skill Power Increase” effect is being applied correctly, and only the value displayed in the Info screen UI is not reflected properly.
