Benevolent Whispers

You touch one willing creature. Once before the spell ends, the target can roll a d4 and add the number rolled to one ability to check of its choice. This replaces a proficiency bonus, if one applies. It can roll the die before or after making the ability check. The spell then ends.

The spell‘s die increases to to 1d6 when you reach 5th level, 1d8 when you reach 11th level, and 1d10 when you reach 17th level.
