Terminus

Terminus is a non-consumable summoning item that is used to start and cancel the Boss Rush event. It can only be obtained by finding it in the Shrine at the bottom layer of the Abyss.

Trivia

 * The word "terminus" means the end, the limit, or the final goal.
 * In previous versions of the mod, the item could alternatively be obtained as a drop from Jungle Dragon, Yharon's second phase.
 * This item can be obtained earlier than intended with a combination of the Abyssal Diving Gear and the Aquatic Emblem, along with some lore items. While the Boss Rush can be triggered at any time, the player will find themselves at a very great disadvantage if they use it before Supreme Calamitas.
