Yeah, but that is following the design of the official Adventure Path. The one
@payn is referencing is Abomination Vaults, which was supposedly after Paizo got their "encounter math figured out" - but it was still very difficult. Other official paths I ran (Age of Ages & Extinction Curse) were downright sadistic.
And I understand wanting thrilling and challenging combats - but not around every corner!
I did an encounter breakdown for the first book of Extinction Curse to share with my group (shortly after they rebelled from the system).
- Trivial encounters: 1 of 49 (around 1%)
- Low encounters: 11 of 49 (around 22%)
- Moderate encounters: 28.5 of 49 (around 58%) [the "0.5" is because one encounter can be considered Moderate or Severe depending on factors.]
- Severe encounters: 8.5 of 49 (around 17%) [the "0.5" is because one encounter can be considered Moderate or Severe depending on factors.]
So that means that 58% of the fights are pretty darned hard and can get scary. But that 17% severe you'd better be ready. Many times they hit you with no warning, and that's when it's exhausting as a player.
Unless Paizo has significantly changed how they design official adventures, I can say they are inappropriate for the challenges I like to present.
