No matter if it's the Energy Gathering Transformation technique of a Domain Emperor Realm expert, or any Incarnation Technique that mimics the Energy Gathering Transformation technique, they all share a common trait: the need to absorb a large amount of Heaven and Earth Primordial Qi. Some even have geographic restrictions, like the Poisonous Ape Technique of the Poison General's Poison Ape; outside the mountain forest, it can't absorb the poisonous Heaven and Earth Primordial Qi from the flora, making transformation impossible.
The Ice Ape Incarnation Technique of the Cold General Yuan Bing is the same. In extremely dry environments like deserts, it cannot absorb any cold water vapor and cannot be unleashed.
