the host can wait at then entrance of the crystal caves or where the Crystalline set is located and everyone could drop red/white summon signs there and as soon as the host summons you you go into the Caves and await for invaders, as soon as its a full house the phantoms descend on each other. the host is in no danger to mobs or death as he is far from the battle n can use binoculars to observe the fight and award points/disqualifications accordingly.

for the tomb of the giants, same thing but drop your summon signs at the top of the ladder where the Large Divine Ember room is located. The phantoms pit fight in the ember room, using the giant sleletons as cover or the host could kill the skeletons for  a free for all no-obstacle arena.

blighttown's swamp could be useful too. Summon signs by the Toxic Mist pyromany corpse and then it could be an open world/arena Deathmatch. utilise the poison for suspense and tension and the host again would not be in any danger as long as the fight takes place away from the Poison/Toxic mist corpse.

the only thing left is how to distinguish people. What could we do to make Competitors recognisable from random invader encounters? Also i guess the host could dress up like Gwyn to show hes the Host of the fight and almighty judge?
