Metamorph organ

Metamorph Samples refer to the 5 types of items from the in-game Metamorph mechanics: Brain, Eye, Heart, Lung and Liver. The itemized unique Metamorph organ (referred as "Greater Samples" in in-game dialogue) only drop from defeating the Metamorph boss that constructed by the player in map.

Mechanics
Each map has a 8% chance to include a Metamorph encounter. The chance is not shared with Master nor Abyss, Blight, Breach and Legion, etc. In the encounter, certain monsters (and map boss) are marked with a green "arrow" on their bodies as well as marked on the mini-map, and the monster health and name bar have a 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 a set of organs to create 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, 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 (unless with 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.

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

 * - the abilities associated with Brain samples are "Lingering"
 * - the abilities associated with Eye samples are "Simple"
 * - the abilities associated with Lung samples have "Medium Delay"
 * - the abilities associated with Heart samples have "Long Delay"
 * - the abilities associated with Liver samples have "Short Delay"

Vendor recipe
Three of any itemized organs can be sold to a NPC to receive a random organ differing from those offered, with random rewards.

Thus, if the players lack Eye and Liver, they should use 1 Brain, 1 Heart and 1 Lung in the recipe to maximize the chance.

Strategy
Metamorphs can be spawned anywhere on the map. 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.

Version history

 * Spawn chance in map has changed to 8%


 * Fixed several Metamorph skills that were using the wrong visual effects.


 * 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.
 * 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 new vendor recipe for Metamorph organs. Three of any organs can be given to receive a random organ differing from those offered, with random rewards.
 * Fixed an uncommon case where Metamorph organs were missing when the area had been cleared.
 * Visual effects from monsters that give organs dying now correctly remain rather than being removed shortly after.


 * Fixed a bug affecting the distribution of organs in Metamorph League. They should now actually drop evenly. We will also be adding a recipe later to help players with excess organs.
 * Fixed a bug in Metamorph League where Tane Octavius would appear before all parts were found.


 * Metamorph samples are now collected automatically when monsters die.
 * Every Map Boss can now be chosen for all organ types for Metamorph League. This will result in an even distribution of the different organs to use in Tane's Laboratory.


 * Fixed a bug in Metamorph League where organs could be placed in the Anointing slot, resulting in a crash.


 * Fixed a bug where Itemised Metamorph Samples could be used in the "Convert this Unique Item" Bestiary recipe.
 * Fixed another case of Unnamed Monster Components dropping from Metamorph targets. This also fixes the issue where the Metamorph UI would display samples that didn't exist.


 * Fixed the Unnamed Monster Component bug. This has temporarily introduced a visual bug where the Metamorph interface will show unobtainable monsters. This will be fixed in a follow-up hotfix.


 * Fixed a bug in Metamorph League where map bosses sometimes did not drop organs.


 * Introduced to the game as league mechanics.
 * In the Metamorph Challenge League, fellow exile Tane Octavius is investigating the source of ill intent in the world; what he calls "The Intrinsic Darkness". Help him by harvesting flesh samples from monsters throughout Wraeclast and combining them to summon powerful, transforming bosses: Metamorphs.
 * Once you reach maps, you'll be able to acquire samples from map bosses in different areas and combine them in Tāne's lab for fights that are extra difficult (but extra rewarding!).
