Amazing supplement, with a high CR Lolth that warrants building a campaign around.

Though I dislike the mechanic where epic monsters know all class spells below a certain level, it makes sense for a literal god.

Four words: Intelligence-based Martial Class. Greatly improves on previously weak mechanics, and adds to the already interesting ones.

Amazing and comprehensive, i only wish it got into the taint mechanic as I dont intend to run a campaign set exclusively in the associated world.
