Izroth spent his time pouring his Essence into the Forever Drinking Leech and Arisia Crystal. Once his Essence reached 0, he would use his Source Chant to begin the regeneration process. Izroth had already completed this action several times and achieved some progress.
As for the Soul Weakness, Izroth was not concerned since he was within the safe confines of the Mystical Realm Palace. Otherwise, how would he be willing to cut his power by 75%?
If it were just against other players, then even if he could not kill them, he was still confident in his ability to escape. However, he was currently marked for death by the Netherworld and a Great Duke of the Pzenium kingdom. Therefore, he could not afford to wander around openly in a weakened state.
