This was even simpler. The players would form two factions, then choose a map. For example, if they chose Italy from Part Five as the map, everyone could engage in free-for-all battles within it.
Likewise, players could only fight using their own physical abilities, combat skills, Hamon, or Stand powers.
The reason Mo Yi had designed it this way and forbidden the use of powers from other worlds in this story event was, first, to train everyone's combat techniques and improve their basic tactical awareness, so that even without Honkai Energy, they could still fight their enemies.
Otherwise, when they encountered the Eleventh Herrscher, the Herrscher of Binding, in the future, once they lost the power of Honkai Energy, they might as well raise their hands and surrender.
The other reason was that although Stand abilities in the world of JOJO were bizarre, human heads were still incredibly fragile. Letting everyone use Honkai powers freely would only strip this dungeon of its proper fun and prevent them from training their ability to use Stands.
Not everyone had the talent to awaken a Stand, but some Stand abilities truly were terrifyingly powerful. For example, The World, which could stop time; Gold Experience Requiem, which could return everything to zero; and D4C, which could manipulate parallel worlds.
If someone like Kiana awakened a Stand of that level through training in this dungeon, fighting a Herrscher one-on-one in the future would be easy. They might even have the power to fight the Herrscher of the End!
That was why Mo Yi had forbidden the use of Honkai powers and made everyone experience this story event as ordinary people.
Only by abandoning the attitude of playing around and treating everything as real could they achieve genuine training results.
Moreover, the world of JOJO emphasized
