Originally, Inala had no idea about the Dance of Annihilation's function. Hence, he didn't intend to steal all the Dance of Annihilations from the Mammoth Ancestor's severed tusk. It was a valuable relic from the past, the only one of its kind.
If it has any significant uses, destroying it by stealing all the Dance of Annihilations from it would be the epitome of foolishness. Besides, it seemed like the severed tusk would replenish the number of Dance of Annihilations in it over time, even if probably required a millennium to generate a new Dance of Annihilation.
Hence, Inala stopped upon gaining three Dance of Annihilations, content since he, Asaeya, and Gannala had one each. That was enough for their needs. And in the future, he planned to understand it better and use it for their benefit.
