Drop Rate Boost: 5✦ Character[]
Notes[]
- Among the above characters, the limited character will not be available in the Stellar Warp event.
- In the Character Collaboration Warp, obtainable 5-star characters include the featured 5-star characters and the custom-selected characters from "Celestial Invitation."
- During the Collaboration Warp period, the limited 5-star collaboration character "Archer (The Hunt: Quantum)" can only be obtained from Character Collaboration Warp "I Am the Bone of My Sword."
- "Excalibur Excelsior" and "I Am the Bone of My Sword" are considered Character Collaboration Warps, and share the same guaranteed drop counter. The cumulative Warp count for a guaranteed 5-star character in any "Character Collaboration Warp" will always be carried over to other "Character Collaboration Warps", but is independent of and unaffected by other types of Warps.
- In this Character Collaboration Warp, there are no featured 4-star rate-up characters. The drop rates for all 4-star characters are equal.
- This Collaboration Warp will be available for a long time, with no scheduled end date.
