This script takes all 675+ Entities in Advent of Ascension and locks them behind a GameStage. This Script requires GameStages and MobStages. I recommend utilizing Gamestage Books and/or Time Stages to further control the release of the Advent of Ascension entities.
Should you opt to you the script exactly as it is now, then simply make sure GameStages and MobStages is installed and then place this in the Scripts Directory and in order to unlock all of the Advent of Ascension entities grant the player the "Advent of Ascension" stage.
