There were two primary reasons for Gannala's current state. The first cause was the increased attacks by the Zingers, resulting in too much of her Prana reserves being stolen. Due to that, she had to overexert herself to consume more food.
All that did was strain her digestive system beyond the limit, as a result worsening her body's condition. An Empyrean Tusk consumed everything, from earth to trees to Pranic Beasts. Its organs were able to extract all necessary substances from the consumed food.
The Empyrean Tusk wasn't merely a living creature but was a biome. But that didn't mean it could consume everything wantonly. It still needed to spend time and effort to digest everything and assimilate the products into its body, just as a human did to food.
