A fun mod, well worth running

It's fun, engaging, and entertaining. No two runs are likely to be identical, right down to the possibility of a high-capability rogue (or other clever player shenanigans) short-circuiting half the adventure. It does have a few editorial issues that DMs need to be aware of and address. It's not explained in the mod, but the DMG guidance on traps is added because DMs are expected to ad-lib additional traps as needed and appropriate.

Probably it's biggest flaw -- and the fact that this is actually it's biggest flaw is a pretty good sign of quality! -- is that a pair of assassins are given a set of scrolls. Scrolls that, firstly, they cannot possibly use as they are not spellcasters, and secondly that -- in the case of the Silence spell -- does not actually do them any good, since it's locked to the place it's cast on, and not mobile.
