Grim Grimoire

Grim Grimoire is a relic located in Inlaid Library. Once collected, it permanently unlocks the Grimoire in the pause menu, in which the player can view all evolutions and unions that have been discovered on their save file, as well as what weapons and passive items are needed to obtain them.
The Grimoire shows evolutions that have been obtained before, and hides any evolutions that have yet to be encountered. However, it does show whether a set of weapons and passives result in an evolution, even if the weapons or passives have yet to be discovered. An exception is made for evolutions that require the Yellow Sign, which are hidden until said relic is obtained.
==Obtaining==
Grim Grimoire is located to the far west of the starting area in Inlaid Library. Its location is tracked by a green arrow on the player's screen. It is protected by 12 patrolling witches that slow you down using a beam attack and shoot bullets at you. Once Grim Grimoire has been collected, it will no longer appear on the map.
Alternatively, the Grim Grimoire can be unlocked in the Forbidden Scrolls of Morbane by casting the Spell "thisshouldhavebeenunlockedbydefault".
