How to unlock the Absolute Symbiosis achievement in Assassin's Creed - Definitive Guide
Sychronization increases as you:
- Rescue citizens
- Visit View Points
- Get ranks reinstated by Al Mualim after you've completed assassinations.
If you complete everything as you go along, this should unlock around your 8th assassination.
