TOWER OF MADNESS Investigate Unspeakbale Horror, without losing your Marbles Literally.

Fail your investigation dice rolls and you will be forced to draw a tentacle from the tower. Any marbles that fall as a result affect your character immediately, whether adding to your discovery total, gaining you spells and knowledge that man was not meant to have, or gaining madness; drop one of the three DOOM marbles, however, and you summon Cthulhu and end the game.
