Tentatool Bad Requirements?

[TheGraeyRebis]

I've tried everything but for some reason, I can't get the Tentatool Bad ending to trigger. Tried it on different planets and different places on the maps. Can't get the arm transformation. Message just says that the pill wore off. Anything I'm missing?

According to the old Flash code, tentacle arms were actually cut, so tentacle legs and a total tentacle score of at least 25 are the only requirements. The chance is rolled upon taking Tentatool while already under its effects, and equals your tentacle score minus half your Willpower, all divided by 80 - so you might just be getting unlucky, or your Willpower is high enough that the Bad End simply can't trigger.
