Akiol's hunch was right. The conditions to activate [Truth Twofold: Rot] were simple but time consuming to achieve. The Undead King simply needed to affect a certain amount of [Truth: Rot] to items. Each weapon that rotted away helped fill this condition.
It now became clearer as to why the undead's weapons were always rusted and dilapidated. Thanks to the Undead King's Truth, the weapons would always be afflicted with rot. Now that the entire battlefield was covered in the--once stone--sand any unlucky individual who touched the sand would find their equipment inflicted with rot.
Moreover this effect seemed to be exceptional effective to those of lower stages. The First Stage combatants the Guilds brought along for the experience found their equipment already falling apart. The Second Stages were able to hold out a bit longer but they were already experiencing the degraded weapons affecting their performance. The one who was suffering the worst however was Torch.
