Sandworms – Dominate the desert

# 🪱 DESERT BEHEMOTHS: SANDWORMS
**Feel the tremors beneath the dunes. Summon colossal inverse-kinematic Sandworms, battle them in full survival combat, or raise your own Mini Behemoth mount!**

**Desert Behemoths: Sandworms** brings massive, multi-segmented subterranean leviathans to Minecraft 1.20.1 (Forge). Powered by smooth client-side interpolation and a 91-segment inverse kinematics (IK) chain, these colossal worms burrow, leap, and crash through desert landscapes in response to surface vibrations.

This enhanced edition overhauls survival combat, biome detection, and companion mechanics—making Sandworms thrilling boss encounters that work seamlessly in both vanilla deserts and apocalyptic sand-covered worlds!

## ⚔️ Overhauled Survival Combat & Boss Bar
Fighting a Behemoth Sandworm is no longer restricted to explosion-only gimmicks:
* **Full-Body Hittable Segments:** All body segments and the head segment feature active hitboxes (`isPickable`), allowing you to strike the worm with swords, axes, bows, crossbows, and tridents as it arcs above the dunes.
* **2x Critical Head Strikes:** Landing melee or projectile hits directly on the **Worm Head Segment** deals double damage toward breaking its armored hide, while body strikes deal standard damage with crunching carapace feedback.
* **Dynamic Top-of-Screen Boss Bar:** Engaging a wild Behemoth Sandworm reveals a clean, numberless **🐉 Behemoth Sandworm** Boss Bar at the top of your screen so you can track its remaining stamina in real time.
* **Explosions & Sonic Booms:** Traditional explosive traps, TNT, and sonic blasts still deal massive chunk damage to the worm’s health pool and trigger custom advancements.

## 🔊 The Thumper & Dynamic Sand-Coverage Spawning
* **Rhythmic Worm-Calling:** Craft and place a **Thumper** on solid ground to send rhythmic seismic waves into the earth, building up *Wormsign* until a Behemoth Sandworm erupts from the depths.
* **Smart Sand-Coverage Detection:** In addition to native Desert and Badlands biomes, the Thumper and vibration spawners dynamically scan a 16-block radius around you. If at least **40% of the surface is covered in Sand or Sandstone**, the Behemoth Sandworm can be summoned in any biome—making it 100% compatible with world-desertification mods like **Sand Apocalypse**!

## 🐾 Sand Leeches & Tameable Mini Behemoth Mounts
* **Sand Leech Companions:** Encounter and tame desert **Sand Leeches** roaming the dunes.
* **Raise a Mini Behemoth:** Evolve and bond with your own **Tamed Mini Behemoth Sandworm**!
* **Safe Riding & Combat Protection:** Mount your Mini Behemoth to traverse the desert at high speeds. Tamed Mini Behemoths never swallow or damage players, friendly Sand Leeches, or their rider, and feature built-in friendly-fire protection so you won’t accidentally strike your own mount while fighting monsters from its back.
