Deceiver

"If this breaks free, it may try to drive you or your followers to insanity."

Deceiver is an Aspect that appears on certain Spirits. When summoning of these creatures is flawed, there is a chance that they may harm the player. This may result in permanently losing a Reason card. Despite what the description says, a Deceiver spirit will not attempt to grab a Follower.

An Escaped Summoning Lies in Wait for You

 * Human sanity is fragile, and this thing is potent.
 * The events of that night will live long in your memory; and for days, the newspapers question residents of the district.

A Spirit of Deceiver 5 or higher has a 70% chance of destroying a Reason card permanently and producing Notoriety; otherwise, only Notoriety will be produced.

A spirit of Deceiver 1-4 would have a 30% chance of destroying your Reason, and a spirit of Deceiver 10 and above would have a 100% chance, but no spirits of these magnitudes exist in-game.
