Nebulous
Legend
Consider the Chamber of Moving Stones in your games. Last night I TPKed a table of eight 2nd-level PCs with the Black Earth Priest (CR 3), Larrakh. The six Bringers of Woe (Bandits CR 1/8) softened-up the party pretty well. But, the real damage was conveyed via the shatter and earth tremor spells.
I think bad PC dice rolls, lack of planning by the PCs and their inability to cooperate as a group started this encounter badly. But shatter sealed the deal. Earth tremor is not a terrible spell, either.
I didn't think an AC of 17 and 45 hit points was that bad, but this party of PCs could not overcame this guy and he laid them low.
Long live Ogremoch!
Good lord. My group of three 3rd levels might get there next session! but they're savvy careful players.
