Wellenkampf

Wellenkampf is a Fabric survival-defense mod for Minecraft 1.21.1. Place an Iron Lure Lantern to establish a base, then right-click it to check wave status, upgrade it, and start each wave when ready. Enemies attack players first; when no player is available as a target, they move toward the lantern and attack it. Waves continue endlessly and grow gradually more difficult, with a 20-minute time limit. The timer pauses while no players are online. Defend your base, strengthen the lantern, and earn rewards including Totems of Undying and random potions. The mod adds custom wave creatures and a dedicated Creative inventory tab. Requires Minecraft 1.21.1, Fabric Loader, Fabric API, and Java 21.
