MCOC 7-Star Carina Tivan becomes available through the final Epilogue chapter, Part 4: Last Struggle, on October 14, 2026. You’ll face three tag-gated bosses, progress through Emperor Doom and Carina encounters, strengthen Carina with special upgrade items and eventually take on Chronoserpent six times.
The last Chronoserpent encounter must be completed with Carina, and finishing the progression awards Ascended Carina. It’s not a standard seven-star crystal pull: the chapter is designed around earning and improving the character while advancing through its boss challenges.
How to unlock MCOC 7-Star Carina Tivan
- Open Epilogue Part 4: Last Struggle after its October 14 release.
- Inspect the chapter’s three tag-gated bosses and check which tagged Champions are allowed for each encounter.
- Work through the Emperor Doom and Carina boss encounters, paying attention to their Unshackled nodes.
- Unlock the seven-star Carina reward through the Epilogue’s progression and claim the special items needed to upgrade her.
- Use Carina against the required Ouroboros bosses as part of advancing her to Rank 5.
- Complete the required Carina boss encounters to unlock the final Chronoserpent sequence.
- Fight Chronoserpent across the six encounters, using Carina in the final one to earn Ascended Carina.
Kabam confirms this overall MCOC 7-Star Carina Tivan progression, but the October preview does not identify all three tag restrictions, the specific opponent order or the exact upgrade item quantities. Inspect the live Last Struggle map before choosing a team or spending upgrade materials.
MCOC 7-Star Carina Tivan: All Last Struggle quest stages and boss requirements
| Stage | Confirmed requirement | Purpose |
|---|---|---|
| Epilogue Part 4 | Enter Last Struggle, available October 14 | Final chapter opens |
| Three tag-gated bosses | Use Champions matching the relevant tag restrictions | Progress through the first boss checks |
| Emperor Doom and Carina | Face their boss encounters and Unshackled nodes | Advance through the chapter |
| Carina upgrades | Collect special items rather than relying on ordinary progression alone | Upgrade the seven-star Champion |
| Ouroboros bosses | Fight required encounters with Carina | Advance Carina towards Rank 5 |
| Carina boss encounters | Use Carina as required | Unlock Chronoserpent sequence |
| Chronoserpent | Six encounters; final one requires Carina | Complete the Ascended Carina challenge |
MCOC 7-Star Carina Tivan isn’t a single-boss unlock. Expect the chapter to test both tagged roster choices and Carina herself. The three tag gates are especially important: a strong Champion without the required tag may not qualify to enter that specific fight.
MCOC 7-Star Carina Tivan: How to upgrade Carina to Rank 5
Kabam’s October 2 stream recap confirms special materials are used to rank up Carina and that Ouroboros boss fights with Carina form part of the path to Rank 5. The official summary doesn’t provide enough detail to state the name, number or location of every upgrade item. Follow the in-game Epilogue rewards as you unlock them.
For MCOC 7-Star Carina Tivan, save those quest-specific rewards and avoid assuming regular rank-up materials are interchangeable. If you reach a locked rank or encounter, check the previous chapter objective and the required Carina participation rather than buying unrelated resources.
Chronoserpent: all six fights and the final requirement
The final boss challenge contains six Chronoserpent encounters. The sixth and final fight requires Carina. The announcement doesn’t identify six distinct attack patterns or phases in a way that supports a guaranteed move-by-move strategy before players can inspect the live encounters.
The MCOC 7-Star Carina Tivan reward depends on progressing through those encounters, so prepare your strongest legal roster for the fights where tags and Champion choice allow it. Keep Carina healthy and ranked as required for the final confrontation, rather than assuming any seven-star attacker can finish the last boss.
Emperor Doom, Carina and Ouroboros bosses
The opening Last Struggle chapter features Emperor Doom and Carina boss encounters with Unshackled nodes. The route then forces you to use Carina against Ouroboros bosses. These aren’t optional detours if you’re working towards the completed, Ascended version of the Champion.
MCOC 7-Star Carina Tivan players should check the Unshackled node descriptions carefully, because those rules can alter how abilities and immunities work in combat. No reliable exact node-by-node counter list accompanies the pre-release announcement; the game itself has the current modifiers.
Rewards from Epilogue Part 4
| Reward | How it is earned |
|---|---|
| 7-Star Carina Tivan | Epilogue Part 4 progression |
| Quest-specific rank-up materials | Progress through Carina’s upgrades and Ouroboros requirements |
| Ascended Carina | Complete the required six Chronoserpent encounters, with Carina in the final fight |
The confirmed headline reward is Ascended Carina. Kabam hasn’t published a complete numerical breakdown of every material in the official summary checked here, so the table names the established rewards without inventing item totals or crystal values.
When does Last Struggle release?
Epilogue Part 4 starts Wednesday, October 14, 2026. The developer announcement establishes the date, but not a reliable universal UK launch hour in the material checked. Watch the game’s quest availability rather than planning for a guessed midday reset.
To pursue MCOC 7-Star Carina Tivan, work through the tag gates and boss encounters in order, upgrade Carina with the chapter’s special items and prepare for the required final Chronoserpent fight. Your goal is to finish with Ascended Carina, not merely unlock the basic seven-star version.
