  Bertrand’s Tome
  Wondrous item
  A
  N
  If you read from this tome, you must succeed on 
  a DC 15 Wisdom saving throw or lose 1d4 sanity 
  points. Completing the entire tome causes you to 
  gain one form of inde�inite madness that can’t be 
  removed by any means short of a wish spell.
  This book contains memory and logic exercises, 
  and its words are charged with magic. If you 
  spend 48 hours over a period of 6 days 
  or fewer studying the book's contents 
  and practicing its guidelines, your 
  Intelligence score increases by 2, as 
  does your maximum for that score. The 
  manual then loses this property, but 
  regains it in a century.
  This book also contains a complex 
  ritual that can summon beings from 
  beyond the Outer Planes. The GM 
  determines the exact nature of the 
  ritual.

  While wearing this brooch, you have 
  resistance to force damage, and you 
  have immunity to damage from the 
  magic missile spell.

  Potion of Invisibility
  Potion
  VR
  N
  This potion's container looks empty 
  but feels as though it holds liquid. 
  When you drink it, you become 
  invisible for 1 hour. Anything you 
  wear or carry is invisible with you. 
  The effect ends early if you attack or 
  cast a spell.
  Sovereign Glue
  L
  N
  This viscous, milky-white substance 
  can form a permanent adhesive bond 
  between any two objects. It must be 
  stored in a jar or �lask that has been 
  coated inside with oil of slipperiness. 
  When found, a container contains 
  1d6 + 1 ounces. 
  One ounce of the glue can 
  cover a 1-foot square surface. 
  The glue takes 1 minute to set. 
  Once it has done so, the bond 
  it creates can be broken only 
  by the application of universal 
  solvent or oil of etherealness, 
  or with a wish spell.
