That's strange. I had mentioned the idea ("the idea," informally, of having Silence-like Stasis) in an S-Z tileschat a couple months ago ... with
exactly the same name.... but I'm glad someone posted it! (I wouldn't have thought to ...)
The original motivation I had for the spell was dual: a utility (stasis is useful; applying stasis to enemies is situationally useful) and buff / debuff to the Distortion brand / translocations users. Currently, while the brand does excellent damage, it causes things to blink and/or teleport, which is annoying, even for Spriggans with polearms of distortion.
However, under Stasis, these movements don't happen, while the damaging effects do - as well as Banishment. So, any enemy in this field that you're whacking with a distortion weapon (preferably a quick blade with a spectral weapon) is going to get many,
many chances of being banished, and is certainly going to be very gruesomely harmed by the crazy localized warping of space.
This is in exchange for sacrificing the use of many translocations and escapes - Blink, Controlled Blink, Haste, Paralysis (enemy), Teleport; the list goes on. It'd be a one way highway to the Abyss or ... death, for the participants.
