The magician allows the universe to flow through zis mind as ze uses it to search for the secrets of existence. The basic use of this spell is to give the magician knowledge on how to perfectly deal with an upcoming situation. Once within the next 8 hours, the magician can choose to treat one d20 roll ze makes as if ze had rolled a 20 on the die. Alternatively, ze can dig deeper into the wellspring of knowledge and permanently infuse zis mind with a fraction of it, choosing from one of the options below:
  • Name a spell of 9th-level or lower. Ze knows how to cast that spell. (DC 21 + the spell's level, minimum 5% chance you can't cast knowledge ever again if you fail)
  • Name a skill or tool ze is not proficient in. Ze becomes proficient in the chosen skill or tool. (DC 25)
  • Name a skill or tool ze has proficiency in and that is not already benefiting from a feature that doubles ze's proficiency bonus, such as expertise. Ze's proficiency bonus is doubled for all checks made with the chosen skill or tool. (DC 25).
  • Name a language. Ze can now speak, read and write that language. (DC 25)
  • Ze instantly learn any information of your choice pertaining to a subject you name. The subject can be an item, place, creature, population, location, etc. and you can learn such things like its game statistics/properties, history, lore, location, etc..
  • Ze may ask the DM a single question, which the DM must answer truthfully and completely to the best of their ability.
When the magician chooses from these expanded options, ze invites danger to zimself. The wellspring of knowledge was not meant for a single mind to be able to handle, and ze risks overwhelming zis psyche or even destroying it entirely. The magician must make an Intelligence saving throw with the DC either included in the options above or determined by the table below.   Equivalent Amount of Information DC Psychic Damage Score Reduction Additional Effects
  • A one-word answer None Required — — —
  • A sentence 1 1d6 1 None
  • A paragraph in a book 5 2d6 1d2 None
  • A page in a book 10 3d6 1d4 None
  • A chapter in a book 15 4d6 1d4+1 You gain a random short-term madness[1].
  • An entire book 20 5d6 2d4 Ze gains a random short-term madness[1].
  • A shelf full of books 25 6d6 3d4 Ze gains a random long-term madness[1]. Furthermore, there is a 10% chance ze is unable to cast this spell ever again.
  • A section of a library 30 7d6 4d4 You gain a random long-term madness[1]. Furthermore, there is a 25% chance ze is unable to cast this spell ever again.
  • An entire library 35 8d6 5d4 You gain a random indefinite madness[1]. Furthermore, there is a 50% chance ze is unable to cast this spell ever again.
If the magician fails this saving throw, ze immediately take psychic damage and zis Intelligence, Wisdom, and Charisma scores are reduced (to a minimum of 1) according to the table above, in addition to any other effects occurring on the table at that DC. The knowledge ze receives is fragmented and may not be complete or accurate. As long as ze suffers this ability score reduction, you suffer the following effects:
  • When ze attempts to cast a spell, the magician must first succeed a spellcasting ability check with a DC of 11 + the spell's level. If ze fails this check, the spell does not cast, and you instead take an amount of psychic damage equal to 3x magician's proficiency bonus.
  • Whenever ze makes an ability check using Intelligence, Wisdom, or Charisma, the magician takes an amount of psychic damage equal to half the number rolled on the d20.
  • As long as none of zis ability scores have been reduced to 1 from this spell, the reduction to each of zis ability scores decreases by 1d4 each time ze finish a long rest.
If one of the magician's ability scores has been reduced to 1 as a result of this spell, zis mind is destroyed. Ze loses the ability to cast spells, activate magic items, understand language, or communicate in any intelligible way. This can only be undone by means of the wish spell or higher.
