From publisher blurb:
Challenge your foes with charm, lore, and blade!
With the new Celtic Bard class for Adventurer Conqueror King and Labyrinth Lord, you can play bards who are more closely based on the original bard as presented in the first advanced edition of the world's most popular roleplaying game, without all the complications and fiddly mechanics. These masters of epic lore can fend for themselves, enchant their foes, and draw upon a smattering of druidic mysteries. Add them to just about any OSR game!
