The two effects synergized in a loop that instantly dropped the temperature by dozens of degrees in their area of effect even when they missed their target.
The Dragon blood flowing in Lith's veins made his Tiamat form weak to cold, so he couldn't let any of the Frozen Wastelands come anywhere close. The situation would have been bad even if he fought the Ishara Elder alone, but Lith also had to stay on guard against Ankhuta's apprentices.
The two younger Isharas were less skilled than their master, but they always remained behind Ankhuta and fired spells on Lith to keep him on the back foot.
The Elder's apprentices moved to close-quarter combat only when Lith was already cornered, making any opening they unwittingly left in their defense impossible for the Tiamat to exploit.
Lith had held his ground until that moment only because Solus filtered the redundant information from the Ears and Eyes of Menadion, sparing him the mental burden that the artifacts would put on him.
