Wither Ascension

Wither Ascension

This datapack turns the Wither into a boss fight. It has scripted attacks, three health phases, and a sword you have to craft to beat it.

The fight is hard. Bring potions, good gear, and a friend if you can.

What it does

• The Wither has three phases based on its health, plus an opening and a last stand.
• It has 17 attacks. Each one shows its name and what to do before it lands.
• The ground changes during the fight, turning into soul sand and blackstone.
• You can craft the Wither-Bane Blade, which stuns it so you can deal damage.

The Wither-Bane Blade

Kill Wither Skeletons until one drops a Withered Core (5% chance, Looting helps). Drop the core next to a Netherite Sword on the ground. The sword keeps its enchantments.

• Hitting the Wither with the blade stuns it for 8 seconds.
• If you hit it while it is charging an attack, you cancel that attack.
• Three of those hits in a row (on Normal) removes 18 HP and stuns it again.
• Right-click throws the blade. It stuns on impact and comes back to you.

The fight

• Awakening — 5 seconds where the Wither cannot move.
• Phase 1 — 100% to 67% health.
• Phase 2 — 66% to 33% health. Minions appear and it casts faster.
• Phase 3 — 33% to 0% health.
• After 3 minutes it takes less damage. After 4:30 it gets stronger again.
• Below 30 HP it moves faster and regenerates health.

Difficulty

/trigger difficulty set 1     casual

After the fight

It drops a Wither Trophy, a Heart of the Sea with +3 attack damage and +5 reach. More trophies and XP come at 5, 25 and 100 kills.

Kill it in under five minutes to get the hidden The Unbroken advancement and 30 levels.
