From publisher blurb:
The Mind Mills is a pamphlet format Five Room Dungeon built with OSRIC and compatible with any OSR game.
Kobol the Visionary is a magician with a reputation for witty repartee, warm hospitality, and fine brandy; a reputation he uses to lure lonely magic-users into his lair, where he drugs them with a unique toxin. His concoction sends their minds across the planes in Astral Form, letting him explore the planes with borrowed senses, and a borrowed life... All to feed his lust for eldritch knowledge. This time, however, he has taken the wrong wizard, and the PCs are hot on his heels... but can they navigate the dangers of The Mind Mills?
I note both ThAC0 and base attack bonuses, as well as ascending and descending AC for easy conversion.
Written as a prequel to Into the Wizard's Hookah
Features four original magic items, and one new monster, along with a sinister reusable villain.
