Hotaka Zetsubou - Soul-Body Separation Technique is an absolute no, how did you think that was going to get accepted? What are the limits of IWR? How long does the Four Blades Seal take to rob all 4 senses and what are 'standard sealing jutsu weaknesses' besides damaging the physical seal itself?
I'll remove it, then.
By "IWR", I assume you mean PWR. Anything significant enough to send a normal person to the hospital for a short stint, such as a deep stab wound or ninjutsu injury, or broken bones, etc.
Four Blades Seal was already inquired of by Yosh, and I responded thusly: Likely one standard "turn" for each sense. Which in Tabletop terms is generally from six to ten seconds. And in addition to damaging the seal, one must make contact with that target to seal them.
