# Simulacrum Simulacrum is a map fragment obtained by combining 300 [[Simulacrum Splinters]]. Using Simulacrum will open 6 portals to Lunacy's Watch, The Bridge Enraptured, The Syndrome Encampment, Hysteriagate or Oriath Delusion. ## 3.16.0 Added 10 additional waves to the Simulacrum, it now has a total of 30 waves. As you can expect, these extremely difficult extra waves are very rewarding and feature escalating chances for a Delirium boss to spawn. With each wave you play, the Simulacrum now has an increasing chance of dropping cluster jewels, and past wave 20, Delirium unique items. ## Bosses - Omniphobia, Fear Manifest - Kosis, The Revelation ## Mechanics The arena is based on one of the town zones, which include Lioneye's Watch (Act 6), The Bridge Encampment (Act 7), The Sarn Encampment (Act 8), Highgate (Act 4/9), or Oriath Docks (Act 10). There are a total of 20 waves of enemies to defeat. Interacting with the Strangely Familiar Entity will summon the wave. Each wave increases the difficulty and rewards. Higher waves add additional monster modifiers and increases the level of Delirium. Once the entire wave of enemies is cleared, it will drop all the loot listed. A Stash is available in the zone, allowing you to transfer items between waves. Starting a new wave will destroy all items on the ground. The Delirium bosses : Omniphobia, Fear Manifest can start spawning at wave 10 and is guaranteed to spawn at wave 15 if he doesn't spawn before, while Kosis, The Revelation can start spawning at wave 15 and is guaranteed to spawn at wave 20 if he doesn't spawn before.[1] Delirium Bosses have increased chance to spawn starting at wave 18[1] and can spawn several times per Simulacrum[citation needed]. ## Item acquisition
