This is a very combat heavy Tier 1. It is Tough. With a little modification, it could easily be a Tier 2 adventure. There is a little bit of roleplaying at the start, but it quickly turns into encounter fest and a slog through a cave. There is some replayability, but only ifthe DM changes the encounters. A couple of us are debating on trying to run this as a Tier2, but it would not be AL legal. I enjoy running this but it is a bit long. The original copy had a misprint that stated APL was 5 first level characters. They upgraded that to 5 third level characters.
