To be forgotten... A fate worse than death. It is as though my very thoughts are breaking, fracturing into tiny splinters... There are secrets buried in my memories, exile. Important secrets ! Save these memories. Preserve them. But move swiftly... Lest you be forgotten. In Synthesis, you will encounter Cavas, recover his lost memories and chain them together to reach valuable rewards, new boss fights and crafting opportunities.

Description on the official Path of Exile website [1]

The Synthesis league and Hardcore Synthesis league were challenge leagues.[1] They ran from March 8, 2019 to June 3, 2019.

In this league, the players will encounter Cavas and fragments of lost memories scattered across the world. Players can enter a memory that leads into a subzone, where they must move fast to stabilize and capture the crumbling memory. These memories are then used in the Memory Nexus to create paths that lead to other pieces of memory. Memories can contain fractured items that contain a permanently fixed mod. Fractured items can also be used to synthesize a new item base with a special implicit mod.

All characters and stashes were moved to Standard league and Hardcore league respectively when the leagues ended. Characters that died in the Hardcore Synthesis league were immediately moved to the permanent Standard league.

After the Leagues ended, Synthesis was not added to the core game. However, the bosses and the accompanying Synthesised uniques were made available via synthesis specific unique maps and Zana missions. The Synthesiser is not available, but Fractured items and Synthesised rare items were made available via other league mechanics.

League mechanic[]

Main page: Fractured item
Main page: Synthesised item

Each regular zone contains a memory sub-zone which can be entered. Once entered, the memory sub-zone will start to decay. Standing too deep within the decay will cause you to be forcibly removed from the sub-zone. To capture a memory, the player must interact with all memory stabilizers within it. Captured memories are used in the Memory Nexus to create paths between other memories. The Memory Nexus can spawn memories containing rewards, memory amplifiers that adds a zone modifier to every connected memory, and boss encounters.
