The Cave

guide

The Swamp Cave is a cave on The Island. The cave contains the Artifact of the Immune, needed to summon the Dragon. A survivor entering the Swamp Cave will notice that the heat is nearly unbearable and the toxic gas will slowly kill you. Come prepared with Ghillie Armor, along with Gas Mask or any 3 pieces ofSCUBA and Ghillie Armor. This will prevent a swift death caused by the extreme heat or toxic gas.

Hazards

Wildlife: Swarms of araneo, meganeura and titanomyrma litter the cave. Titanoboa and the occasional megalania can also be confronted, as well as a large leech pool. Possibly the biggest threat are the arthropluera which can rapidly destroy armour and breathing equipment. On 1.0 difficulty, most of these creatures range between level 120 and 360. Achatinas can also be found but offer no threat.
Poisonous air: Breathing equipment including gas masks or a full set of SCUBA gear (including the mask, tank, leggings and for some reason the flippers), as the toxic fumes within the cave can rapidly cause death.

What You'll Be Dealing With

assembled from what lives in this cave 6

Armour damageTorporPoison and gasAmbushSwarmsHeat

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.
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.
Leech — Attaches and drains health, and can give Swamp Fever.
Burn it off at a Campfire or use Sweet Vegetable Cake; it will not detach otherwise.
Megalania — Climbs walls and ceilings, so it attacks from above where a mount cannot follow, and its bite applies a stacking torpor.
Check the ceiling. Stimulant for the torpor stacks.
Titanomyrma — Swarms and applies a small amount of torpor per bite.
Bug Repellant.

Not a threat: Achatina, Meganeura
