The drow came out of the basement to menace them last night. They were mostly sorcerers, clerics and vampires with equivalent class levels. And vampires. I probably would have run a competent game if you ever answered your phone to talk me out of these things.

Anyhow- I transposed Spider for Crab since PF is not D&D. Drive the differences home! The driders were drihorseshoecrabs.
