Full sync account-wide rewards and save files - full explanation
TLDR - Full synchronization and NG+ rewards are intended to be granted to all saves account-wide once earned on any save. BUT it is a glitched feature and you may not actually get all of the rewards in each save file.
I just finished an Ultimate Assassin full sync run after having previously completed full sync at Master Assassin difficulty prior to Valley of Memory releasing. The second screenshot is back in my original save file (non-NG+) and I am wearing the Rayhan White Costume with Obsidian Rayhan Dye and the Skull Emblem, all of which are full sync rewards. (I am a little disappointed that the Skull Emblem is so subdued.)
Proof that this is intended functionality:
AC Mirage Title Update 1.1.0 Nov. 17, 2025 - List of Bug Fixes -> Gameplay ->
- "All claimed rewards are now linked to the player account save. For instance: any reward claimed in Permadeath will now be accessible to all the saves on the player's account."
Ubisoft Support "Full Synchronization feature in Assassin's Creed Mirage"
- "Your rewards will be automatically available in your in-game inventory for any save."
On my Ultimate Assassin full sync save (which is locked into permadeath mode), I properly have every reward. But here are the glitches I have encountered on my original (non-NG+) save:
- Missing 5 of the 6 Grey dyes rewarded for completing Master Assassin full sync (Grey Initiate of Alamut is the only Grey dye that I have). This glitch may be personalized to me because I completed Master Assassin full sync prior to the 1.1.0 title update which made the rewards account-wide.
- Missing the Blue Bayek dye that should be a reward for completing an NG+ (non-full sync). I saw a post a few days ago where another user was experiencing this glitch.
- Not really a full sync issue, but for posterity's sake I will list that the Oasis Initiate of Alamut dye from Ubisoft Connect is still bugged and has never been granted to anyone.
Tips for completing Ultimate Assassin Full Sync:
- Desert Scorpion Pack. The armor and dagger are best-in-game.
- Animus mods. Unlock through Animus Sequence and turn them on when you start the full sync run. Bonus that the Animus Sequences are great practice for a full sync run.
