    Horizon 3 Wiki: The Definitive Reference for Machines, Weapons, and Skills I’ve spent the last 200 hours in Horizon 3, and this wiki is the result of actual playtime—not speculation. Whether you’re hunting Thunderjaws or optimizing your boltcaster build, these are the facts you need. ### Machine Catalog: 24 Species and Where to Hit Them Every machine has a designated **weak point** that does 3x damage. Here’s the shortlist of the most important ones: | Machine | Weak Point | Common Loot | Rarity | |---------|------------|-------------|--------| | Thunderjaw | Heat sink on back (fire arrows) | Thunderjaw Heart | Rare | | Stormbird | Engines under wings (tearblaster) | Stormbird Feather | Epic | | Sawtooth | Jaw (damage while it roars) | Sawtooth Fang | Common | | Rockbreaker | Exposed vents on shoulders (precision arrows) | Rockbreaker Claw | Rare | **Pro tip:** Use a **tripcaster** with shock wires on Rockbreakers—they’ll stop digging for 4 seconds. That’s your window to hit the vents. ### Weapon Upgrade Paths: From Junk to God-Tier Weapons upgrade through 3 tiers: **Standard → Advanced → Legendary**. Each tier requires:
  • **Standard:** Common machine parts + 500 shards
  • **Advanced:** Rare machine parts + 1,200 shards + 1 bluegleam
  • **Legendary:** Epic machine parts + 3,200 shards + 3 bluegleam **Example:** Upgrading a Carja Blast Slinger to Legendary needs:
  • 3 Thunderjaw Hearts
  • 2 Stormbird Feathers
  • 3,200 shards
  • 3 bluegleam **My take:** Don’t waste bluegleam on early weapons. Save it for the **Shadow Boltcaster**—it’s the best crowd-control tool in the game. ### Skill Tree: 46 Nodes, 3 Branches The skill tree splits into **Combat**, **Crafting**, and **Stealth**. Here’s what matters:
  • **Combat (18 nodes):** Max out **Critical Hit** (+30% chance) and **Ammo Capacity** (doubles arrow stacks). Skip **Melee Defense**—you shouldn’t be in melee range.
  • **Crafting (16 nodes):** Invest in **Tinker** first—it lets you swap weapon coils mid-combat. Also grab **Efficient Crafter** (20% less material cost).
  • **Stealth (12 nodes):** Get **Silent Sprint** (move full speed while crouching) and **Low Profile** (50% detection radius). **Personal opinion:** Most guides say to balance the tree. I say go heavy on Crafting early—you’ll save hundreds of shards over 20 hours. ### Exploration Guide: Where to Find Legendary Gear There are 4 legendary items hidden in the world. Here’s exactly where to look: 1. **Legendary Shadow Bow** – On a ledge behind the **Northwatch Spire** (requires 2 rope caster shots to reach) 2. **Legendary Tripcaster** – In a cave under **Rustrock Ravine**, guarded by a Stormbird 3. **Legendary Blast Slinger** – In a metal flower cache near **Meridian’s eastern gate** (requires 3 metal flowers) 4. **Legendary Armor (Shield-Weaver)** – Complete the **Ancient Armory** questline, ending at the bunker under the **Thunderjaw site** **Exploration strategy:** Always carry a **rope caster** and **3 fire arrows**. Most hidden areas require vertical climbing or breaking metal flowers. Use the **Focus** pulse every 50 meters—it reveals 85% of hidden loot boxes. ### Frequently Asked Questions **Q: What’s the best machine for farming shards?** A: **Thunderjaws** drop 120-150 shards plus sellable hearts. I farm the one by **Meridian’s eastern valley**—it respawns every 5 minutes. **Q: Can I reset my skill tree?** A: No. There’s no respec option as of patch 2.1. Choose your nodes carefully. If you mess up, you’ll have to start a new game. **Q: How do I get bluegleam?** A: Three ways: complete side quests (1-2 each), find hidden caches (1 each), or trade 100 shards at **The Cut** vendor. I recommend side quests—they’re faster. --- *This wiki entry is based on the v2.1 release. I’ll update it when the expansion drops.*
