About this project
What does War Wither add?
This mod adds a powerful new boss—the "War Wither"—which is stronger and more agile than the standard Wither.
If configuring settings, the War Wither will replace the Wither spawned via Soul Sand. You can enable/disablethis feature in the configuration settings. When disabled as an independent boss, players can transform a vanilla Wither into the War Wither by using a Nether Star on it (or by adding the warwither:change_wither_to_war_wither tag).
Configuration files allow you to adjust the War Wither's attributes and enable/disable damage limitation mechanics.
This mod requires Jerotes Warehouse as a prerequisite.
