Full Synchronisation Requirement - Do not lose more than half of your health
It’s possible to do this without medicine, but keeping some at hand will be really helpful! Draw your weapon of choice and use counters and executions to clear out the attacking guards.
Head up the stairs and meet another group of Templar guards. Use the same strategies again and if you happen to take damage top up your health with medicine – you’re going to need it.
The smoke billowing inside the cave will slowly drain your health, and it’s up to you to use Eagle Sense to find your way across the city with your vision obscured to the exit, and when you health drops to around 60%, use a medicine to top it up to get the most use out of each medicine. It shouldn’t take you more than one or two medicines to keep you sustained as you head for the exit, and as shown in the video it is possible to do it without using any – they’re just in case you get lost.
The difficulty is traversing the confusing city layout without proper vision or a minimap. Follow the moving crowds; they usually head the right direction towards the exit. Also, you can follow the waypoint, and the path gradually should lead you down, then back upwards out of the cave.
Once you exit the cave, you’ll have to fight a group of guards including an Almogavar axe man again. The easiest method of taking them out (provided you don’t want to just bomb them of course) is to counter one of the smaller, faster Templars and then use an execution streak to bring down the Almogavar as priority.
Head to the marker for a cutscene and then the Memory will end.
