Onslaught is a commissioned mod by codetaylor made for the Rebirth of the Night modpack. We'll adjust and add more to this description overtime, but a quick overview is that it is an extensive invasion mod made to allow for as much customization as possible. Inspired by Terraria invasions, there is a visible progress bar and mobs defined in the config will spawn and seek the player out until they are killed whenever an invasion night occurs. The invasion ends after all mobs are killed.
