Mystic Sumatra Art, according to its Founder's intent, was created as a technique capable of being wielded by all Pranic Beasts.
Typically, Pranic Beasts never needed a cultivation technique, for any benefits associated with a cultivation technique was something their physique could naturally do.
Information Slips? They had the means genetically imbued to transfer information through parts of their bodies, acting similar to Information Slips.
Skills? As long as they perform a certain action enough times, no different from regular training, they'll grow the muscles necessary to unleash an effect with greater potency, which is the essence of a Skill.
Prime Skill? Reaching this level enables in the Pranic Beast a possibility to mutate, for only when a Skill gets taken to its absolute extremity is it called a Prime Skill. And once it can individually interact with Prana and express its effects onto Sumatra, it becomes a Nature.
