PFS #2-14 The Chasm of Screams

[Russell Akred]

I am curious, why is it on one of the encounters there is an effect that only succeeds against creatures of 6HD or less? The tiers are 7-8 and 10-11 so none of the party should be that low. Maybe a multi-class wizard's familiar or a multi-classed character's animal companion but otherwise it seems useless except as a story element at best.

[Mark Moreland]

The rules element you refer to didn't prepare for a party as experienced as those playing this scenario, then. Characters and monsters in the world don't always know the level range their adventure is going to fall into.
