The Stasis Stone, assuming that parry stasis will one day be patched out, a stone should be added to replace it.

The stone would use a new pose (similar to guard), or just be applied on parry, and the stone would hold the structure in place no matter what modifier is applied to it for 3 seconds. The structure can still be broken as well. It can be held and flicked and when it is released, any momentum added to it will be released.
