Version 4.5: Double SP Patch
Version 4.5 looks set to be a fan-service heavy update with two special (SP) variants releasing in the same patch.
- Robin SP is expected in Phase 1. She is rumored to arrive on the Remembrance path. Leaks suggest she will serve as a powerful support piece, potentially shifting team compositions and replacing certain units in optimal setups. Her kit appears to build on her original Harmony identity with new mechanics tied to Remembrance.
- Aventurine SP is slated for Phase 2. He is expected on the Elation path (with possible Preservation influences). Some reports point to a Quantum element and strong follow-up attack (FUA) focus. This version could complete certain mono-element or team archetypes.
This double-SP structure has players planning their Stellar Jade savings carefully, as both units are highly anticipated.
Version 4.6: IPC and Ten Stonehearts Spotlight
Version 4.6 shifts focus toward the Interastral Peace Corporation (IPC) faction, specifically the Ten Stonehearts.
- Pearl (full name often associated with the Ten Stonehearts) is the most consistently mentioned character for this patch. She is expected on the Elation path. Leaks describe her as a potential sustain unit. Earlier testing reportedly had her kit ready as Preservation, but current information points to Elation. She could bring new gameplay options for Elation teams.
- Sugilite is frequently paired with Pearl in 4.6 rumors. Another Ten Stonehearts member, he is also expected on the Elation path. Limited details exist so far, but his release would expand the playable Stonehearts roster significantly.
One additional unknown Elation unit has been mentioned across leaks for the 4.5 to 4.6 window, though no name or details have surfaced yet.
Version 4.7: New Character Debut with Model Update
Version 4.7 is shaping up to introduce a fresh playable character with notable visual changes.
- Nihilux is the standout name tied to this patch. She is expected to receive a playable model glow-up compared to her current NPC appearance. This follows the pattern seen with other characters who transitioned from NPC to playable status. Leaks link her to Elation themes, the Aeon Aha, and the Mourning Actors faction. Her story significance in the Planarcadia arc could make her one of the more lore-heavy additions in the later 4.x patches.

What Players Should Know
The upcoming patches emphasize SP variants of popular characters alongside new additions from the Ten Stonehearts and Planarcadia storylines. Elation is receiving heavy investment across multiple patches, while Remembrance gets its first major limited unit in Robin SP.
Pull planning will be crucial. With back-to-back limited units in 4.5 and continued releases afterward, many players are already saving aggressively.
Stay tuned for more reliable information as patches approach. Official livestreams and beta testing will eventually confirm or adjust these leaks.
