The Catalyst Mod is a new game+ style add-on for the Calamity Mod. It currently adds various new items and enemies, some based on the superboss Astrageldon.

The mod is planned to add much more content in the future, such as new biomes to explore and more superbosses.

Please note that this mod is intended to be used in brand new playthroughs. Not doing so may damage your experience with the mod.

If you have any issues with this mod, its Discord server is the best place to have your problem addressed. The comments section on this page is NOT the place to engage in any discussion of the sort.
