Onixya roared loud enough for all to know that she was coming. Players on the side of the Ash King panicked, it was not known to Dave beforehand as the skeletal dragon the Undead King rode to battle had wreaked havoc in their ranks, and now add to it a fully-fledged living dragon, the situation turned sour before she could even arrive.
The Earth Titan dug both its hands in the ground, pulling up a boulder the size of a small town then threw it right in the Ash King's direction. The latter was unable to dodge, if he did, the boulder would break right through one of his four ramparts and allow Undead easy access to his dominion.
The Ash King clapped both hands together in a thunderous explosion of sound, and then pulled them apart with exertion, creating a sword of fire. The motion was fast enough that he managed to wield the sword of fire and swing at the boulder, sundering it to ashes before it could do any damage.
