The Arcane Compendium of the Lost Realms

Compiled by an extinct order of sorcerers, the Compendium is said to hold the keys to accessing realms that have been lost to time, planets and planes that have been erased due to time paradoxes, and navigating changes being caused within the past.

Among the text are pages that function as a spell scroll.

Time Stop
9th-level transmutation

Casting Time: 1 action
Range: Self
Duration: Instantaneous

You briefly stop the flow of time for everyone but yourself. No time passes for other creatures, while you take 1d4 + 1 turns in a row, during which you can use actions and move as normal.

This spell ends if one of the actions you use during this period, or any effects that you create during this period, affects a creature other than you or an object being worn or carried by someone other than you. In addition, the spell ends if you move to a place more than 1,000 feet from the location where you cast it.

SPELL SCROLL RULES (DMG p. 200)

When using a spell scroll, the spell must be on a caster's class spell list to use as an action (no need to provide any spell's components). Otherwise, the scroll is unintelligible.

If the spell is on a character's class spell list but of a higher level than can normally be cast, the character must make an ability check using the usual class-related spellcasting ability (Intelligence, Wisdom, or Charisma) to determine whether it is cast successfully. The DC equals 10 + spell's level. On a failed check, the spell disappears from the scroll with no other effect.

REQUIRED SPELLCASTING ABILITY CHECK
* Cantrip (Common) ... DC 10
* 1st Level Spell (Common) ... DC 11
* 2nd Level Spell (Uncommon) ... DC 12
* 3rd Level Spell (Uncommon) ... DC 13
* 4th Level Spell (Rare) ... DC 14
* 5th Level Spell (Rare) ... DC 15
* 6th Level Spell (Very rare) ... DC 16
* 7th Level Spell (Very rare) ... DC 17
* 8th Level Spell (Very rare) ... DC 18
* 9th Level Spell (Legendary) ... DC 19

Once the spell is cast, the words on the scroll fade, and those pages within the book fall out as dust.
