You Could Do Better

You don't allow those around you give up, with some magic and a little bit of hope. When an ally within 60 feet of you fails an ability check or saving throw, you can cast this to give them a d8 to add to the roll, potentially causing success in the check or saving throw.

At higher levels: The die type changes to a d10 at 4th level or higher, and again to a d12 at 6th level or higher.
