Finally, after half an hour of bombardment, Ezkalor, Eneru, Nalzrig, and Zyphon joined the fray and cast High-Level spells that made things difficult for Ezio.
They could have swarmed in using their overwhelming numbers to overpower the defenders, but after the Kraetor Empire's interference, the High-Level officers of the Elven Army decided that they should conserve their manpower just in case the Young Empress changed her mind and attacked them from behind.
Soon, one of Drauum's Giant Boulders landed squarely against one end of the City Walls, destroying it completely. The Elves didn't rush in immediately, but continued their bombardment. King Minos was greatly disappointed by the Elves' cautiousness because it prevented him and the Minotaurs from fighting them in close combat.
