The Cave

guide

The Great Trench is Valguero's wyvern trench, with entrances at 8.7 / 79.2 and 9.2 / 70.9.

It holds the Artifact of the Skylord at 13.4 / 72.6, on a small island at the bottom of the largest room — and it is also where Valguero's wyvern eggs are.

Hazards

The temperature inverts as you descend: the trench above is frozen and snow-covered, and the cave below runs 90–125°F (32–52°C) with open lava. One set of gear will not cover both.
Fire and Ice Wyverns nest here, and taking an egg brings the flock.
Entering the fire wyvern dwellings has been reported to crash the game at random.

Recommended Equipment

Outside: Fur Armor and high Fortitude.
Inside: Ghillie Armor or Desert Cloth Armor, again with high Fortitude.

What You'll Be Dealing With

assembled from what lives in this cave 7

Heavy carnivoresArmour damageTorporColdHeat

Mantis — Uses whatever weapon it holds, so its damage depends on what it picked up, and it is fast.
Arthropluera — Its ranged acid attack damages armour directly — primitive Flak breaks in one or two hits — and armour damage cannot be repaired if the piece is destroyed.
Wear Hide rather than Flak and carry Fiber and Hide to repair. Kill it at range; it out-damages armour faster than you out-heal it.
Araneo — Webs you in place from range, which stops you kiting and stops a mount fleeing. Its bite applies torpor.
Kill it at range before it closes. Bug Repellant makes it ignore you entirely.
Pulmonoscorpius — Torpor per hit, higher than almost anything else its size, and it is fast.
Bug Repellant, and Stimulant for when it lands hits anyway.
Titanoboa — Applies heavy torpor per bite and is quiet enough to reach you before you see it.
Stimberries or Stimulant on your hotbar. Two bites will drop an unprepared survivor.
Ice Wyvern — A freezing breath that slows you and drains stamina, on top of flying and hitting hard.
It is the least dangerous of the four in raw damage; the slow is what gets people killed by everything else in the room.
Fire Wyvern — Breathes fire in a cone that keeps burning after it lands, and it flies.

Not a threat: Dung Beetle
