Murk, the Horned One and Weaver of Fates, has accelerated you on the path of learning and knowledge. When you roll a training die with advantage, you roll three dice, instead of two, and pick the highest one.
Tome of the Abstruse. You always know the precise location of your personal notebook as long as you are on the same plane of existence. The book has become magical, functions as a spellcasting focus for all spells you can cast, and cannot be destroyed or damaged except by you or with a disintegrate spell. The book generates six blank pages each day.
Spread the Knowledge. As part of a long rest, you can infuse spells onto parchment. When you do this, you choose any number of spells from the spells that you know. Each spell must be a 1st-level spell or higher, but no higher than 5th level, and they must have a combined level no higher than half your character level (rounded up), and must have a casting time of 1 action. You then create scrolls imbued with the chosen spells; you don't expend spell slots but you must provide the material components. A creature holding one of these scrolls can use an action to activate the scribed spell if they have an Intelligence score of at least 6 and can read the scroll. The spell is cast at the level you chose during its creation, and uses your spell attack bonus and spell save DC. The creature that activates the scroll decides the targets of the spell. A scroll vanishes once used or when you use this boon again.
