What it actually takes to kill
The multiplier is the number that matters. At 0.33×, it soaks damage — 120 HP behaves like roughly 364, so it costs about 3× the ammunition its bar implies.
In practical terms: about 6 shots from a Flintlock Musket — the 66-damage ceiling weapon, so treat that as the best case. With a Crossbow at 40 damage it's about 10, and every one of those shots is silent.
That puts it 6 of 14 by raw HP among the creatures anyone has managed to measure.
What the codex says
Amphibious, ancient, and drawn to where the sea meets the land — straight out of Lovecraft's own menagerie rather than invented for the game.
Standing orders
The worst honest fight in the bestiary: 120 HP behind a 0.33× multiplier means it soaks about three times the ammunition its health bar implies, and it does not give up the chase. Long eyes at 45 m too. Engage on your terms or not at all.
How it finds you
Detection runs on two separate senses and this creature's are uneven: sight 45 m, hearing 40 m. Breaking line of sight is the reliable move; brush works better than distance. Full detection notes are on the survival guide.

Deep One questions
How much HP does the Deep One have in The Mound?
120 HP, and it takes 0.33× damage — so the effective pool is closer to 364. These are community measurements cross-checked against the 1.0 build; the game never shows you a health bar with numbers on it.
How do you kill the Deep One?
About 6 Flintlock Musket shots at 66 damage, or 10 crossbow bolts at 40. The crossbow is slower but silent, which usually matters more than the extra shots — gunfire winds the forest's awakening timer.
Why does the Deep One take so many shots?
Its 0.33× damage multiplier. The 120 HP figure is misleading — effectively it behaves like roughly 360, so a 66-damage musket needs about six hits rather than two.
