Not sure if this a new or old thread, so I might have said this already: that Ogre encounter is pretty rough.
It's from a small scenario specifically designed to sell the game. Yet it pits the 1st level heroes against a monster who easily instagibbs any hero on a critical*. Not just "knocks unconscious" but outright kills. Regardless of that hero's precautions.
Not sure I see the wisdom in that...
*) the pregen heroes in the module itself have 15, 16, 17 or 19 hp and thus die instantly on taking as little as 30 damage. An Ogre deals (1d10+7)x2+1d10 damage on a crit, which easily amounts to more than 30 points (its maximum is 44). This doesn't only happen on rolling a natural 20 in Pathfinder 2 - anytime the Ogre beats the hero's AC by ten points or more its a critical. With a +12 attack modifier against a typical AC of 17 that happens on a roll of 15, 16, 17, 18, 19 and 20.
I don't mind a regular game pitting a fresh set of heroes against a lethal monster. But this is specifically a demo game you run to entice new players. Not sure getting turned into bloody pulp without having done anything wrong is the best way to achieve that...
Normally a single foe two levels above yours is a reasonable challenge. A Moderate one in fact, which is nothing to concern ourselves with. But there's nothing normal about this encounter. The Ogre packs one of the most brutal level 3 criticals, and the heroes are at their most fragile at first level. I submit the dev didn't think things through here. It would have made a lot more sense to feature a fight against a River Drake or a Lion or something with a significantly lower chance of dealing ~35 damage in a single blow. Not to mention using two creatures instead of one (which would remove the instagibb risk entirely), I dunno an Orc Brute riding a Warg maybe.
