Mystic Thread Strike

Mystic Thread Strike (操糸万妖斬) is an art used by Souei.

Abilities
It imbues the 'Insta-Kill' from his Shadow Striker Unique Skill with several other negative status effects inside of Sticky-Steel thread. The threads are capable of bypassing most resistances and even tear the target's spiritual body to shreds.

Trivia

 * In That Time I Got Reincarnated as a Slime: Isekai Memories, the "Souei [Spy in the Shadows]" unit uses this as a Secret Skill.
