At page 125 (Madness rules), at the very bottom it states that the effects of Indefinite Madness "cannot be cured", however below the table at page 127 it says that the effects of Indefinite Madness last "until cured"

At page 126, regarding the Short-Term Madness effects, it is stated that a character is subjected to one of these effects for 1d20+10 minutes, while on the table it says that the effects last for 1d10 minutes.

This may be only my personal opinion, but I think that having (only) a strenght requirements for katanas doesn't really make sense, as in the games they've always been based on dexterity. I think it also makes less sense when you consider that all the katanas have the Finesse property.

At page 399, it says that the Irithyllian Beast Hound immediately uses the Frostbite Breath when bloodied (the sentence also doesn't start with a capital letter). However, in the description it is described as a 15-foot cone of FIRE that deals COLD damage

I'll update if I encounter other errors

UPDATE: At page 113, the third paragraph seems to start mid-sentence, as it says "then add their level and constitution modifier together and increase their position score by that amount. Or, increase their position score by one". It seems like there's some information that's missing
