I ran the adventure in the Tom Moldvay Basic Rulebook today. The characters got through the first level of the dungeon, besting the Goblins and Hobgoblins and a Crab Spider. They are now resting up and getting ready to climb through the trapdoor into the catacombs. Great fun!
I'm doing this adventure with a new group. Some of the players have never played D&D or any rpgs. They had a great time creating characters, both new and experienced players. I think they had the most fun choosing proficiencies, which is a big part of the appeal of ACKS for me.
There are two Elven Spellswords, and Elven Enchanter, a Shaman, a Mystic, a human Fighter, and a Thrassian Gladiator should be joining us for thre next session.
I had an encounter with giant bats, and the Elven Enchanter, who had the Beast Friendship proficiency, managed to get a good reaction roll and took the bats on as henchman!
