Other improvements and fixes
Improvements
- Character optimization display, split up: the nameplate rank icon display and the 'show other players with the same appearance' setting can now be set separately for the field, the Abyss and Rift of Time and Space skirmishes. Both are under Settings > Graphics > Optimization > Character Info Display.
- Maximum Arcana held drops from 1,100 to 500. If you are over the cap you must remove the excess by extracting.
- Arcana extraction gains a new item, 'Superior Training Arcana (Soul-bound)', and no longer yields 'Mysterious Crystal (Soul-bound)'. Progress already accumulated is removed, and Mysterious Crystals will be paid out later depending on whether you had progress.
- The number of Pet Chests (Soul-bound) you can open at once is increased.
Fixes
- Divine Traces that Halloween decorations had left in unreachable spots at the Dawn Legion Base in Verteron and in Zumion Village are moved to reachable positions.
- Fixed the 'Movement Controls' category appearing twice in Settings > Key Bindings.
- Fixed the Trial 'Fire Temple' occasionally counting as failed when you kill the boss at the same moment the dungeon expires.
- Fixed abnormal screen output in multi-window mode on some foldable devices.
- Changing your weapon appearance during the Halloween weapon idle animation now stops the animation.
- Transfer Stone Fragment (Unique) and (Heroic) (Soul-bound), obtainable from the Season Shop, Expedition Exchange Shop, Growth Support and achievements, are replaced by Transfer Flame (Unique) and (Heroic) (Soul-bound).
Recovery and restoration
Because a material-conversion formula for Masterpiece Remnant (obtainable in Expeditions and Transcendence) was added on October 7, Masterpiece Remnants are paid out retroactively to each character's cube for items deleted, sold or restored under the pre-update play history. If you sold the item, Silentium (Soul-bound) is taken back for each set amount of sale value.
