The Big Book of Madness

The Invocation marker advances one space during the Monster Phase, and you must apply the effect of whatever space it lands on (apply any Curse there, or—if it reaches the Invocation space—check whether any Curses remain and apply the page's failure or success effect, then move the marker to space 1 and turn the page). (See page 7.)

Yes — the support pool is shared: any player may use cards from any player's support to pay an Action cost, but when a supported card is discarded it goes to the discard pile of the player who originally placed it in support. (See pages 8 and 12.)

A Spell is exhausted when activated and cannot be used again until it is refreshed during your next Concentration Phase at the start of your turn. (See page 6.)

You may learn a face‑up Spell from the Library by paying 2 Elements of the same type; place it face‑up in front of you and you may use it immediately, but you are limited to five Spells and must destroy one (remove it from the game) if you learn a sixth. (See page 9.)

You all win if you turn all pages of the Grimoire and vanquish the final Monster; you lose if the Madness stack is empty when you must take a Madness, if you fail to vanquish the Monster on the last page, or if all players are eliminated by Madness. (See page 10.)
