Witheria Mod brings a massive robotic boss to your game. After you defeat a normal Wither, you get the chance to summon this giant machine. The battle tests your dodging and fighting skills with special attack animations so you know what move comes next. You can practice the fight on an easier mode or take on the true difficulty for a massive challenge. If you win, you get powerful rewards and even the chance to ride the metal beast.

Features:

- Gives you a choice between a practice mode and a true difficulty mode before the fight begins.

Boss Attacks:
- Throws bombs from the sky that cause massive explosions if you do not destroy them in time.
- Fires mortar shells that leave red warning marks on the ground before they hit.
- Shoots main cannons straight at you, forcing you to use blocks for cover.
- Drops floating mines during the second phase that explode after a short delay.
True Difficulty Changes:

- Makes the boss track players from any distance and follow them across different dimensions.

How to Use:
- Defeat a normal Wither to trigger the prompt for the new boss fight.
- Choose your difficulty level before the boss spawns in.
- Watch the boss movements closely to dodge attacks, as building blocks and moving fast are key to winning.
- Defeat the true difficulty version to get the Witheria commander item.
- Use the commander item on the friendly, inactive boss to ride it, and press W to move forward.
