You begin announcing out loud a combat encounter that is about to begin, announcing each of the fighters in combat, and generally acting as if you were an announcer for a battle in an arena, or the announcer of a sporting event. After this, you choose one point you can see within 60 feet of you, and choose up to 20 willing creatures you can see within 150 feet of you. Out of the point you chose, you make a radius that is no less than 10 feet, but no greater than 150 feet, and out of it, a magical aura appears and engulfs the land and willing creatures within it, creating a simulated terrain that is visible to all creatures.
Once the spell is cast, and the terrain is set, combat initiates and all creatures roll initiative. Any spell effects they may have put up before the spell was finished casting remain on these creatures. In addition, each creature declares allegiance to one side of combat, which can be either their own, with other creatures, or likewise. Regardless of who they choose to ally with, combat ends when only one alliance in combat remains, or if the spell ends before that. Whilst in this simulated arena, outside creatures cannot harm creatures under the effect of the spell, and inside creatures cannot harm creatures outside of the effects of the spell. Likewise, creatures under the effect of the spell cannot interact with any objects, terrain, creatures or likewise not originally engulfed by the spell, or outside of the spell’s range. Creatures under the effects of the spell cannot be harmed by creatures or objects unaffected by the spell. Creatures under the effect of the spell have their physical body transported to one space they have seen within 60 feet of the exterior of the spell, and their physical body lies there unconscious until the end of the spell. If they take damage while the spell is still active, they are removed from the spell, and they regain consciousness where their physical body is.
When combat is initiated in the spell, each creature has whatever abilities, HP, and likewise they had before the spell was cast. However, when the spell ends, all abilities, HP, and likewise expended during the spell’s usage are given back immediately. This also applies to charges on magic items.
