Thanks Orladdin, you reminded me of the stunt Murphy has, and that's exactly how it works.  As to the degree of blocking, a 0 shift hit is still a hit, so it wouldn't have been successfully defended, and Riposte wouldn't trigger.

Centarion: You're posting without a book in front of you I think, which I am guilty of all the time, but reading from the book:
A severe cancels 6 stress, not 4, that's a moderate.  The stunt as written in YS grants you two additional milds. (pg 152), which (in the absence of anything else modifying your consequences) is equal to 3 milds total, or 6 stress.  That's a severe.  If they heal simultaneously, that's clearing a severe at the speed of a mild, and still having a real severe in reserve.  Is that how it works?  Seems powerful for 1 refresh.

When a character takes a stunt allowing them to sustain multiple mild consequences at the same time, how do those consequences heal?  Simultaneously? Consecutively? Or does recovery take one scene per consequence, so they're staggered simultaneous?
