Hiding is a darkness-aligned transcendental skill. It can hide multiple nearby objects. It is similar to invisibility, but it also hides sound and touch. This skill consumes vigor over time.
Upon using another transcendental skill, the cloaking wears off first before the other transcendental begins. However, if the sura is a 5th-stage rakshasa with both Sky and Darkness attributes, then it can use the most powerful level of Hiding which does not wear off.[1]
Pingara uses this skill to keep himself, Sagara, and Riagara out of sight while Sagara plots to get Maruna (who recently tried to attack them) to help them.[2][3]
