All battles between champions occur in the Gladiator's arena, where only allies can be used as support cards. The event lasts until your next turn. (Harmful)

"Gladiator's Arena is where fighting is done by the brave and strong ones, those who are not afraid to die or shed blood on the floor. Some fight for family, for their people or tribe. Some struggle for money, power, or greed. Some want glory, women, or feasts.

The battles are hard, the battles are bloody, but there is always one victor who comes on top. The one who crushes their opponents with a sword, a magic spell, or mysterious powers, all that matters is winning in the Gladiator's Arena. Fighting is just a cycle of a brutal bloodbath that will continue throughout centuries until the end of time itself."
