The underground dinosaur biome represents one of the most exciting endgame challenges in Hytale. With the arrival of Update 1, the ecosystem has evolved: predators are smarter, and the environment is more hostile. With adequate preparation and the strategies presented in this guide, you will hunt the Cave Rex and collect rare materials like a true prehistoric predator.
The Dinosaur Biome: Where to Find These Forgotten Giants?
If you dream of crossing paths with a Tyrannosaurus or collecting unique materials, you need to know where to look. Hytale’s dinosaurs do not roam the surface; they reside exclusively in a unique underground biome, nestled beneath the volcanic lands of Zone 4 (Devastated Lands).
This is not a simple cavern, but a lush, bioluminescent Forgotten Jungle. You will generally find this biome between Y levels 30 and 40. A clear indication that you are in the right place is the appearance of glowing plants in the dark and distinctive roaring sounds.
Location (Step-by-Step Guide)
- Reaching Zone 4: This volcanic desert requires traversing the previous zones. Prepare significant provisions.
- Spotting Volcanoes: Look for volcanic peaks (red dots on the map). Volcanoes with golden circles often indicate better entrances.
- Spawn Point: It is imperative to place a bed or campsite on the surface before descending.
- Rapid Descent: The “lava diving” method (using daggers for sprinting) still works, but look for natural entrances to save your healing items.
- Depth Y 30-40: Keep an eye on your coordinates. This is the precise layer where the lava gives way to the jungle.
Dinosaur Species: Know Your Prey
The biome is now home to species with complex behaviors, often using light to hunt.
| Dinosaur | HP (Est.) | Behavior | Main Loot |
| Cave Raptor | ~100 | Aggressive, pack hunter, high jump | Medium Leather, Meat |
| Cave Rex | ~400 | Field Boss, uses a luminous lure | Heavy Leather, Meat |
| Trillodon | 200-250 | Defensive (Neutral), frontal charge | Heavy Leather, Meat |
| Dimetrodon | N/A | Aquatic ambush, toxic | Meat |
| Pterodactyl | ~16-60 | Aerial, aggressive | Blue Feathers, Meat |
| Archaeopteryx | ~16-60 | Aerial, passive/fleeing | Blue Feathers, Meat |
Tactical Threat Analysis
- Cave Rex (The Lure): The Rex possesses a glowing appendage on its head (like an anglerfish). In the dark, if you see an isolated light, do not approach: it is a trap.
- Raptors: They are never alone. Their jumping ability has been buffed; they can now climb roots to flank you.
- Dimetrodon: Often overlooked, this amphibious reptile prowls in underground lakes. It is hard to see underwater and attacks swimmers.
Hunting Strategies and Preparation
Essential Gear
- Armor: Onixium is highly recommended to tank hits from the Rex (which deals ~30% HP per hit).
- Food (Nerf): Warning! Since the update, raw fruits/vegetables only provide Regeneration I. You must bring cooked dishes (stews, pies) to survive.
- Weapons: A longsword (for Raptor groups) and a crossbow (mandatory for Pterodactyls).
Combat Guide: Cave Rex
This 400 HP behemoth requires method:
- Line of Sight (LOS): The update fixed attacks clipping through walls. Hide behind large indestructible trees to force the Rex to reposition and interrupt its charge.
- The Dance: It turns slowly. Wait for the attack, dodge to the flank, strike 2-3 times, and back away before the tail swipe (AOE).
- Terrain: Never fight in a tunnel. Lure it into a clearing.
Note on Taming
Contrary to rumors, there are no dinosaur saddles in the current Vanilla version. The game uses a “Trust” system (feeding to temporarily pacify), but you cannot turn them into permanent mounts without using Mods.
Loot and Farming Optimization
Once the zone is secured, it is the best source of Heavy Leather in the game.
- Heavy Leather: Vital for Tier 3/4 backpacks and endgame armor. The Rex and Trillodon are the only reliable sources here.
- Blue Feathers: Archaeopteryx drop these often. Useful for crafting special arrows and accessories.
- Processing: Don’t forget that leather must be treated on a Tanning Rack before it is usable.
Troubleshooting: Common Problems
Problem: Cannot find the biome?
- Ensure you are in a “New Chunk” (an area never visited before the Update).
- Check the Y layer (30-40).
Problem: Overwhelmed by Raptors?
- Seek high ground or deep water (they swim slower than you do with flippers).
- Use the Trillodon: If you position yourself behind a Trillodon, Raptor attacks can hit it and trigger a battle between the dinosaurs.
Problem: Lack of healing?
- Lifesteal or regeneration potions are more effective than raw food since the nerf.
