Metamorph league

"Take a clean knife and cut a sample of flesh. Repeat. Four times. Mix the five samples in aquathaumatic solution. Heat. Stand back. The intrinsic darkness will make itself known. Observe its anger, its aggression. Observe its changing form, never comfortable to stay in one shape for long. It will try to kill you... Best not let it. Plunge the clean knife repeatedly... Hm. Try more heat. More! Perfect. Only every living creatures to go.

In Metamorph, you'll meet Tane Octavius, a master alchemist who studied in Oriath. Exiled to Wraeclast for killing his teacher, Tane searches for what makes the "self", by using his learned alchemical knowledge to assemble monster essences. He hopes to find a cure, or perhaps just the source, for what he calls "the intrinsic darkness" that led to his unforgivable violence."

- Description on the official Path of Exile website

The Metamorph league and Hardcore Metamorph league are past challenge leagues. They launched on December 13, 2019 along with the release of the Conquerors of the Atlas expansion.

In this league, the player meets Tane Octavius. He tasks the player with gathering parts from various monsters, which he uses to create a Metamorph. Metamorphs are enemies that constantly change forms, using the moves of enemies it acquired the parts of, even unique bosses. Metamorphs drop loot based on the parts used, which can include Catalysts that give a quality stat to jewelry, increasing the magnitude of specified modifier types and the likeliness of rolling those mods.

All characters and stashes were be moved to Standard league and Hardcore league respectively when the league ended. Characters that die in the Hardcore Metamorph league were immediately moved to the permanent Standard league.
