The Submerged Lands are inhabited by creatures twisted by the past catastrophe. The roster spans sea and land, with night-time variants explicitly more dangerous. Use this page as the counter list — match the threat you are seeing to the family below, then load the matching harpoon variant and medicine before you close in.

Sea threats
| Threat | Behaviour | Counter |
|---|---|---|
| Harpooner-style predatory fish (e.g. Harpooner, Bloodgill) | Contest the line during a cast; can pull a catch off the rod | Reinforced harpoon keeps the catch and damages the predator |
| Tentacle monsters | Surface at night near the boat, with frequency roughly twice the day rate in the demo | Fire Harpoon or Toxic Harpoon for flesh; clear water with the spotlight module first |
| Leviathan-class encounters (e.g. leviathan skull landmarks with glowing eggs) | Slow, large, scripted; one direct kill is unrealistic | Plague Harpoon for stacked status; brace for a long fight and bring Blood Pack |
The Harpooner and Bloodgill family are the predator fish you meet while fishing — they will pull a catch off the line if you persist with the rod. Switch to the harpoon on the next cast and they go from contesting your catch to a manageable combat.
Land threats
| Threat | Behaviour | Counter |
|---|---|---|
| Scavengers around abandoned buildings and caves | Hit and run; drawn to noise | Harpoon at range, fall back to a barricaded location |
| Rare scripted monster attacks on the surface | Triggered by long stays in exposed spots at night | Barricade, then engage with the elemental match (Fire for biological, Frost for fast movers) |
Do not stay outside after dark unless the area is barricaded. Scripted monster attacks hit the player in the open, and the warning signs (gulls leaving, ripples further out) are easy to miss in the dark.
Night threats
Healed and shielded boat
Hull Armour (Mk I) installed, full fuel.

Barricaded finish line
Route ends at a settlement dock or a barricaded location.
For how those four preparations turn into a planned night run, see the DREADMOOR night expeditions guide.
Continue the night run
Treat the four preparations above as the night-run checklist that scales with the threat level you are heading into.
