Boat in a Bottle drop rate?

[ilhwang77]

After I grabbed all oddities in expedition except Boat in a Bottle and completed pirate questline, I slaughtered every pirates in Port Ceto, Port Crag, and on sea. I only got 3 Boat in a Bottle after that slaughter, which means pirates are slaughtered for 3 Oddity XP.
 Randomness of Underrail is really frustrating. Usually I don't bother Oddities which I have to kill or pickpocket(JKK pen, Foul Mouth Wash, etc), this time I planned a completionist playthrough, and really regret after all. I've killed over 350 mutants and mutated dog in Depot A in order to get Acid Cyclopean Eye, but pirates would not respawn, which means my playthrough ended in failure.
 It's weird that there's Oddity which needs to kill one major faction's every man and woman twice throughout two playthrough by exporting a character.

Ive always gotten every ship in a bottle on every playthrough, whether Im genociding pirates or picking their pockets.  There's also the peg legs in various places in their territory and some carry eyepatches.

I can confirm that the Boat in a Bottle is really low and I’ve also killed all the pirates I can find without getting all the oddities. Idk why but it’s really hard to get even one without geocoding the pirates.

You cannot grab Boat in a Bottle by pickpocketing. The only way to get Boat in a Bottle is killing pirates and looting their corpses.

I finished this playthrough today, and got every Oddities except Antifreeze Protein Injector(I encountered three masters in this playthrough), 2 Boat in a Bottle, and Acid Cyclopean Eye(It seems that Two-headed Mutant can't spawn in this playthrough).

Said with such conviction, yet wrong all the same.  How about that.

I know it can drop over 5 pieces. I've acquired 5/5 on another playthrough.
I just said it's drop rate is extremely low, low enough not to get 5/5 on one playthrough if you are unlucky.

After quick check with my another character who sided pirates, now I know I can get it by pickpocketing, which means wiki page about this oddity need to be modified.
I learned something new, thanks.

It is pretty low; I got my last one on the very last map with pirates left.  You have to check them all.

I've checked several times, and just checked once again. No one left.(Actually there are only 3 alive human beings in expedition region now, Todd, Ferry man, Yngwar.)

Just in case, these maps all have pirates (X means theres also an interior or two)

I checked all of them including Fetid Marsh just in case(corpse of Razor's friend), found nothing.

Ive never had that happen.  However, in future runs, to guarantee it doesnt, you can farm the pirate jet patrols that spawn infinitely.
