It was late at night and not many people were online, in the end, Mu You only managed to gather Capricorn and Libra, but that was enough.
[You've received energy transfers from three directions.]
[You have entered Cell No. 4771 and locked the door.]
[You have summoned the Spike Serpent Guard, Fire Giant, Shadow War Eagle, and Netherworld Demon Child.]
[You have summoned the Troll War God and Legendary Witch Doctor.]
[The cell features a Paralysis Field, weakening creatures in there by 90%, making their attacks feeble and inducing drowsiness.]
This cell is effectively a natural Duel Field. After death, respawning can only happen inside the cell, so you don't have to worry about the opponent escaping.
The only limitation is the weakening effect in here, but it applies equally to everyone. Furthermore, Mu You primarily relies on magic damage.
[Phantom Thief Valen has teleported behind you and used 'Sap,' attempting to gain the upper hand.]
