Metamorph has been removed from the core game. Itemised Metamorph Samples will be deleted upon logging in.
Catalysts are now rewards from Ultimatum, and are affected by Map Item Quantity.
Catalysts are no longer offered as Ritual Rewards, or a reward type for Delirium Rewards.
Mysterious Incubators can no longer drop Catalysts.
Expedition Remnant modifiers in Expedition sites that grant Runic Monsters and Chests a chance to drop Catalysts have been replaced with modifiers that drop Heist Contracts instead.
Reduced the amount of Catalysts obtained from Heist Chests, Expedition Chests, Betrayal Chests, and Vaal Unique Strongboxes, as well as the amount of Catalysts offered by Tujen.
Added a new Ultimatum Cluster which contains the Brave The Tower Notable Passive. This Notable causes the Ultimatum Boss to drop a full stack of random Catalysts, and Ultimatum Encounters in your Maps to have 30% increased chance for the final Round to include a Boss. The 4 small Passives in this cluster each cause Ultimatum Encounters in your Maps to have 10% increased chance for the final Round to include a Boss.
Accelerating and Unstable Catalysts can now be obtained from Catalyst sources outside of Ultimatum encounters.
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.
