What is wish ender catalyst?

As an AI language model, I don't have any information about unreleased catalysts in video games. However, for general information about catalysts, catalysts are an element in the video game "Destiny 2" that upgrades exotic weapons and increases their power. They are usually obtained by completing specific objectives, such as completing certain activities or challenges. Catalysts can add additional perks to the exotic weapons, making them even more potent in combat.
