By this juncture, the two opposing forces had drawn close enough for combat to be joined in earnest.
The spellcasting adepts were the first to launch their assault.
Behold, the halos of elemental power flickered and danced. Fiery orbs of incendiary might, crescent-shaped blades of wind whistling with a cyan hue, and arrows of water, glimmering with a cerulean sheen, all soared aloft to assail the ranks of the undead.
"Boom."
"Click."
"Tsk, tsk."
The fireball detonated with a thunderous roar, engulfing the foremost undead in a searing conflagration. The resultant shockwave rippled outwards, buffeting the surrounding undead horde.
In a flash of cyan luminescence, the wind blades sliced through the air, cleaving a swath through the undead. Those caught in the direct path of the blades were instantaneously shattered, their skeletal remains scattering upon the ground like so much detritus.
