Grimoire

A grimoire is a foul tome filled with and protected by foul skaven (or chaos) magic. They have a very disturbing appearance, with moving skin and eyes. The protagonists risk taking these in order to take them out of the hands of the skaven.

Gameplay
Up to 2 grimoires can be present in a level. They are typically well hidden, often requiring that a player solves a puzzle to access them. Once a grimoire is picked up, it fills a player's potion slot. The maximum health of each player in the party is decreased by roughly 30% for each grimoire held by the team, but this decrease in health can be minimized by wearing trinkets with the curse protection passive property. If a grimoire is dropped or the player carrying one it killed, the grimoire is lost, and the health penalties are removed.

Due to the decrease in party health, grimoires significantly increase the difficulty of a map. Though full book runs are common, it is polite to ask the party before taking a grim.
