Most Soma categories make heavy use of RNG manipulation sequences (commonly called "manips") to guarantee that certain items or souls always drop from specific enemies. This allows runners to utilize routes which would otherwise require impossibly low drop odds to succeed.

Overview

Whenever a new game is started or a save file is loaded, the RNG seed will always be reset to the same value. Depending on the room Soma loads into, it is sometimes possible for the player to perform standardized movements and actions to advance RNG deterministically to a value which produces a desired drop from a specific enemy.

Julius mode is unable to perform manips, as it has no method to suspend and reload the game.
