Scroll Sage

You accumulate and exploit spell scrolls, recognizing the worth they provide. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• You can read and cast a spell from a spell scroll even if it isn't on your class's spell list.
• You can scribe a spell scroll even if you aren't proficient in Arcana, and you reduce the time and cost to do so by half.
• As an action, you can expend and cast a number of spell scrolls up to your proficiency bonus at once. The spells must require an action or a bonus action to cast, and can't require concentration.
   Once you use this action, you can't do so again until you finish a long rest.
