Del’s Accelerated Comprehension

You choose one document, book, or contract that is within range. Once you have touched the document you know its contents as if you had spent hours reading over every detail. If you spend a number of minutes equal to the level this spell was cast at reading the document, any skill check DC associated with the document is reduced by an amount equal to the spell slot used to cast the spell. If used on a spell scroll, this reduction of DC applies to the check in order to cast said spell scroll. The reduction in skill check DC’s associated with this document persists until you take a long rest.

At Higher Levels. When you cast this spell using a spell slot above 1st level, the number of minutes required and Skill Check DC reduction increase to match the level it is cast at.
