For consistency's sake, you should change the first step of Stunned to something other than Slowed, since you have a separate category for Slowing. It just doesn't make a lot of sense.

Maybe something like Stymied or Distracted?

Also Blighted seems to be carry a bit more narrative weight than Impaired or Disabled and seems a little out of place. Blighted, to me, should belong in a separate category for Cursing, and should be replaced with something like Inhibited.
