Enhance Memory (4e Ritual)
From D&D Wiki
You enchant your own mind, allowing rituals and spells to be bound to it.
|Arcana or Religion (no check)
The Enhance Memory ritual only affects you if you have the Spellbook class feature or Ritual Caster feat. On completing the ritual, your mind is considered to be a ritual book or a spellbook with a capacity of 16 pages. The effect of the ritual is cumulative, increasing the capacity of your enhanced memory by 16 pages, to a maximum of 128 pages.
The spell can also be used to clearly remember other things, as if it were a sketchbook or notebook instead of a ritual book.
