Bestow Boon

When you cast this spell you touch a willing creature, and choose the nature of the blessing from the following options:

• Choose one ability score. While effected by this spell, the target has advantage on ability checks and saving throws made with that ability score.
• While effected by this spell, the target has advantage on attack rolls.
• While effected by this spell, the target can make a Wisdom saving throw at the start of each of its turns. If it succeeds it can end one spell, or magical effect on it.
• While the target is effected by this spell, it's attacks and spells deal an extra 1d8 radiant damage.

At the DM's option, you may choose an alternative effect, but it should be no more powerful than those described above. The DM has final say on such a blessing's effect.

At Higher Levels. If you cast this spell using a spell slot of 4th level or higher, the duration is concentration, up to 10 minutes. If you use a spell slot of 5th level or higher, the duration is 8 hours. If you use a spell slot of 7th level or higher, the duration is 24 hours. Using a spell slot of 5th level or higher grants a duration that doesn't require concentration.
