Ace of Spades

The caster yells out in a particularly gruff voice, "Ace of Spades!", conjuring the song Ace of Spades by Motorhead to be played at very high volumes, alerting everyone that all you need is the Ace of Spades. When this is cast, the caster rolls a d8, and if it lands on a 5, 6, 7, or 8, then increase a chosen stat by 3 for 30 minutes. But if the roll lands on a 1, 2, 3, or 4, then decrease a chosen stat by 3 for 30 minutes. The entire point of this spell is to be a gamble. (EX. If a bard rolls an 8 on the d8 roll then they can increase their strength by 3, making it easier to succeed on strength checks for a time. On the flip side of this, if they roll a 1 on their d8, then they can decrease their strength stat if there is no need to have a high strength stat at the time).
