Creator notes
Undermagic II is a datapack that expands the progression of the game with unique new gear and challenging boss fights. Inspired heavily by the Calamity Mod, this pack is a re-imagining of the original from 2019 and is currently in an early release state. - Raid the Demonic Keeps, new Nether structures housing fearsome Demons - 5 unique weapons: swords, spears, bows, and projectile melee for a wide variety of playstyles - New armor set with unique properties - Obtain items through expanded progression, from diamond sidegrades to new vanilla boss drops and beyond - An intense boss battle against Demon General Maxon; intended to be challenging but fair, configurable via the world difficulty - Complete in-game guidance via the Demonomicon (obtain by entering the Nether for the first time, or use /trigger um2.demonomicon to read) This is an early release. There is much more to come, including both new and returning content... Join my Discord server for discussion and any support needs. I love to hear what you have to say! This pack uses the Smithed Crafter library by rx, Nexus, and many others. You do not need a seperate download, it's included in the files. Thanks to them! Most textur
