# Simulacrum Splinter Speaking of which, every now and then you will find Simulacrum splinters. The mysterious entity will create strange encounters based on warped versions of your own memories. Monsters in Simulacrums come in waves that get progressively more difficult. You'll receive loot at the end of each wave, and you'll have to make the decision to leave now or continue on, facing up against even tougher foes from the mist. The bosses you will face as you get deeper into the Simulacrum are truly terrifying. Still sane, Exile? If you can complete a Simulacrum, you'll gain points for the Delirium section of the Atlas skill tree.
