Athena's Blessing

Boon:

Athena blesses a target creature, granting then a bonus 1d4 which they can add to one d20 roll before the end of the duration. Once the dice has been used the spell ends.

Bane:

Athena curses a target creature, condemning them to failure. The caster of Athena's Blessing(or the summoner if it is cast by a familiar) chooses one d20 roll that the target makes before the end of the spell. If the spell is activated the target must roll a d4 and negate the total from the d20 roll.
