BlackJack Circle

BlackJack Circle causes you and any number of people you can see up to 10 feet of you to be put into an indestructible, inpenetrable 5 foot diameter sphere. Everybody in the sphere will start playing blackjack and the victor gets to take gold from everyone else within the sphere. Once blackjack is finished the sphere also disappears ending the spell.

People inside the blackjack circle cannot leave the circle, attack anyone within or outside the circle, or interact with the circle or anything else while in the circle and can only play blackjack. People outside the blackjack circle cannot interact with the circle either, and victims of the spell cannot choose not to participate in the blackjack circle or they will instantly lose.

At higher levels the caster of the spell gets advantage on blackjack checks by rolling half the level the spell is casted at rounded up number of dices and taking the highest number. Those who are not experienced with blackjack will be forced to roll at disadvantage.
