Necklace of Heaven’s Powerful Healing

Because of Gilbert's injury, his movements were a lot slower than in his peak state. His presence didn't make a big difference in the battle and the groups were still in a stalemate. Furthermore, the remaining Level 5 Underworlders seemed to have inexhaustible stamina. They have been continuously swinging their weapons without rest, but their strength didn't decrease at all!
