The sanity checker is one of the first items revealed on the Eldritch Tab. Its sole purpose is to let the player keep track of their current warp levels. When held, it shows a GUI in the top left corner of the screen displaying the varying types of warp the player has. The darkest purple band is permanent warp, while lighter purple is normal (formerly "sticky") warp, and pink is temporary warp. The gold bands represent the required warp levels for the Eldritch Epiphany and Eldritch Revelation. If the meter "overflows", the brain atop it will appear cracked; this level is required for comprehending the Crimson Cult book (WIP).
Middle Item: Thaumometer.
1x zombie brain.
1x mirrored glass.
