What You'll Be Dealing With

assembled from what lives in this cave 4

Armour damageTorpor

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.

Not a threat: Cat, Dung Beetle
