Metamorph league

Affliction Patch Notes

• Metamorph has been removed from the core game. Itemised Metamorph Samples will be deleted upon logging in.
• The following Metamorph Uniques have been added to the core drop pool: Astral Projector, Fury Valve, Mother's Embrace, and Warrior's Legacy.
• The Awakened and The Transformation Divination Cards can now be found in the Gardens, Haunted Mansion, Palace, Tower, and Underground Sea Maps, as well as the Death and Taxes, Hallowed Ground and Maelström of Chaos Unique Maps.
• The Sextant modifiers that cause an area to contain Metamorph Monsters or cause Catalysts dropped by Metamorphs in your Maps to be Duplicated can no longer roll. Existing Voidstones or Charged Compasses with these modifiers have had this replaced with a modifier that causes your Maps to contain Ultimatum Encounter.
• The Shifting Ire has been removed from the Foundry Map Boss fight. Existing Shifting Ires that have been captured in a Ritual Vessel are now "Ciergan, Shadow Alchemist" instead.

Ultimatum Patch Notes

Metamorph Changes

• Added an Accelerating Catalyst, which adds quality that enhances Speed modifiers on a Ring, Amulet or Belt.
• Added a Noxious Catalyst, which adds quality that enhances Physical and Chaos Damage modifiers on a Ring, Amulet or Belt.
• Added an Unstable Catalyst, which adds quality that enhances Critical modifiers on a Ring, Amulet or Belt.
• Metamorphs created in Tane's Laboratory now deal 10% more damage and have 80% more health.

Delirium Patch Notes

Metamorph Mechanics Added to the Core Game

• Metamorph, and Tane, can now be found once you reach maps. Each map has a 10% chance to be populated with monsters who can drop Metamorph parts. Tane will appear in your hideout once you have completed his Pound of Flesh quest. He will no longer appear in towns, misanthrope that he is.
• You can now find Metamorph Scarabs from various sources. Each scarab guarantees Metamorph monsters will appear in an area, with higher-tier Scarabs causing map bosses to drop additional Metamorph parts.
• Added a Sextant modifier which will also cause maps in the associated Atlas region to contain Metamorph monsters.
• Made a number of improvements to specific Metamorph behaviour situations. For example, Metamorphs with only ranged skills will now still attempt to move closer to the player, whereas previously they would stand in place.
• The "maximum power" effect on the bar to the right of the Metamorph panel no longer plays if it is impossible for the fight to drop an itemised organ.
• Added a line to the reward box when the Metamorph will drop an itemised organ.

Introduction

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.

• Mechanics

  • Each map has a 8% chance to include a Metamorph encounter, which is rolled independently from other chance-based encounters, such as Masters, Abyss, Blight, Breach, Delirium, Essence, Ritual, rogue exile, Legion, Smuggler's Cache, Strongbox, The Sacred Grove, etc. In the encounter, certain monsters (and the map boss) are marked with a green "arrow" on their bodies as well as marked on the mini-map with a circular green icon, and the monster health and name bar have a similar green circle. Upon defeating these monsters, they drop organ samples which are automatically collected. With a full set of samples - Brain, Eye, Heart, Lung, and Liver - players can construct a Metamorph unique boss monster based on the combination they have used by spawning Tane Octavius and his Metamorph Vial using a button on the bottom right (PC default keybind: V). Tane spawns automatically once you've collected every organ in the zone.

  • Players can use any combination of the collected organs to create the Metamorph monster. Each monster is made up of 5 organs, and players must select one of each type before constructing the Metamorph monster. Each organ determines the attacks the Metamorph uses, as well as the monster modifiers it has. Sometimes an organ will contain an additional item drop bonus. Moreover, a meter to the right fills based on sample rarity, which increases the monster's overall stats and item drops. Organs from higher rarity monsters will give larger increases to this meter. If the meter is filled as well as using at least one map boss sample (which have the same orange item color as unique items), the Metamorph will drop an itemized organ sample, named after the name of the map boss, which can be placed in player's inventory. Note that in some cases, even in a fully cleared map, there are not enough rare and unique organ samples to fully fill the meter, due to external factors such as map rarity, map mods, map tier and pack size. Only one Metamorph boss can be constructed per a map instance (the exception being in the Valdo's Rest region with the Repeated Experiment Atlas passive skill), and only the itemized organ(s) can be transferred out of the zone instance. Player can boost the drop of itemized organs by using Metamorph Scarab. Each specific Metamorph monster can only drop a single type of itemized organ (though it can drop more than one of that type due to atlas passives or scarabs), regardless of how many orange-colored organs are included in its construction.

  • The Metamorph monster will have a combination of attacks and abilities depending on the organs used (each organ notes one or more attacks/abilities it grants the monster). In addition, as the Metamorph is battled, it will summon a substantial number of minions to assist it, which can be lethal even on their own if the Metamorph is defeated before them.

  • Itemized samples can be used in the Metamorph Vial in Tane's Laboratory. A full set of itemized organs can be used to construct a Metamorph there. The mods on the itemized organs indicate additional items the Metamorph will drop. Note that no more organs drop in the lab.

• List of Metamorph organ samples basetypes

  • Metamorph Brain - the abilities associated with Brain samples are "Lingering"

  • Metamorph Eye - the abilities associated with Eye samples are "Simple"

  • Metamorph Lung - the abilities associated with Lung samples have "Medium Delay"

  • Metamorph Heart - the abilities associated with Heart samples have "Long Delay"

  • Metamorph Liver - the abilities associated with Liver samples have "Short Delay"

• Vendor recipe

  Any three itemized organs (even of differing types) can be sold to a NPC to receive a random organ differing from those offered, with random rewards. Thus, if the players lack Eyes and/or Livers, they should use 1 Brain, 1 Heart, and 1 Lung in the recipe to maximize the chances of receiving an organ they need.

• Strategy

  Metamorphs can be spawned anywhere on the map using the UI button in the lower right. Using different strategies with placement can make defeating them easier.

  • For characters that can hit enemies off screen with ranged skills, placing the metamorph in an open area will make it easier to hit them far away and get away.

  • For characters that use melee hits, placing the metamorph in the smallest area you can find will prevent large amounts of enemies from hitting you at the same time.

  • If the atlas has a watchstone in the maps region with a sextant modifier that says "Area has additional packs of monsters that convert" there will be traitorous totems on the map that give the player and minions auras. Spawning the metamorph near these totems will give the player and minions auras during the metamorph fight.
