Cursed Seal of Catastrophe

This is a cursed seal employed by Miyuki Ōtsutsuki as Kali on her Heralds of Catastrophe. The seal grants the recipient a portion of Kali's corrupted power, turning them into malevolent, sadistic, violent underlings.

Usage
The seal itself already passively augments the recipient's overall physic ability, alongside granting them chakra and its usage. Additionally, the seal can be activated to further inject more power into the user, further augmenting all their capabilities while often causing visible mutations, very similar to the second phase of Orochimaru's cursed seals. It's also suggested that the seal grants immortality and an ability akin to Hidan's Curse Technique: Death Controlling Possessed Blood.

Trivia

 * The mark itself resembles the katakana for Jashin (ジャシン), which could mean Jashin (or the concept of) and Kali are somehow related, possibly even one and the same.
 * Having into account the seal's suggested abilities mirror those of Hidan and Kali's reputation as an "evil" goddess, it's likely Jashin and Kali are the same concept. Although Jashin is usually identified as a male deity, it might just be that Kali's legend has been distorted somehow or purposedly changed.
