Publisher's blurb: DUNGEONCRAWLERS to DRAGONSLAYERS! is a simulacrum of the “basic/expert” or “B/X” version of the most famous fantasy roleplaying game of all time published in 1981. That version was presented in two books, but this work combines previously released Open Game License content for them into one volume. DUNGEONCRAWLERS to DRAGONSLAYERS! also includes several appendices of alternate rules so you can better tailor the game world to your style of play. Unsheathe your sword, prepare your spells, and steel your nerves! Your adventure starts now!
