Memory fragments which you've captured in zones are used in the Memory Nexus to create paths. A memory can have two to four paths leading out of it. The path is based on where the Memory Stabilisers were located in the memory.
Memories can be placed in the Nexus by interacting with the Stabiliser that does not lead into another memory. They can be placed as long as all its paths connect to empty space or paths leading into another memory. In other words, you cannot place a memory in a grid if at least one of its paths connects to a memory but their paths don't align.
You can "pre-place" a memory by placing a memory fragment from the Nexus map, but this does not physically place the memory into the Nexus; they are placed once you interact with the Stabiliser leading into it.
A memory can be entered a certain number of times before it starts to decay. At one charge left, the memory will decay once you enter it.
You can right click a memory fragment you've placed to delete it.
In memories that have one charge left, entering it will start the decaying process, similar to fragmented memories found in zones. Falling too deep within the decay will teleport you back to the last Memory Stabiliser you've interacted with. Decaying zones have a chance to drop fractured items. Clicking on a Stabiliser will collapse the memory and transfer all dropped items to that location.
Decayed zones will persist within the instance until the instance expires or manually removed by right clicking it on the Nexus map or interacting with a Stabiliser leading into it.
Memory fragments can contain zone modifiers like maps. They can have additional modifiers added via two methods: Memory Amplifiers and Memory Modifiers.
Memory Amplifiers grants bonuses to memories placed in that specific grid. Amplifiers are marked with a yellow square in the Nexus map.
Memory Modifiers spawn in Distant Memories like the ones containing treasure. Interacting with a Memory Modifier will apply a zone modifiers to all connected memories, including ones connected to the Nexus center.
Distance Memories spawn randomly within the Nexus. Distant Memories contain treasure or a boss. They have one path leading into it and decay once entered. Their zone level is equal to the memory connecting to it.
If you want to exit a Distant Memory and continue exploring, do not interact with the Stabiliser next to the treasure. Once the chests or Memory Modifiers are opened, enter into the decay and respawn next to the bridge entrance then collapse the memory.
Maximize the value of Memory Modifiers by immediately replacing decayed memory paths with a fresh one.
