What defensive spells would you want to cast, if you were in Dumble's army?

Carol responds:

are you sure that you mean defensive spells? I thought those were
pretty much limited to Protego and Expelliarmus. However, (assuming
that we're going for humor here and not passing moral judgment on
people who give each other boils or antlers or elongate their teeth),
I wouldn't have minded a spells in which people turn each other into
animals ("Don't turn me into nothin' unnatural!" Oops, wrong book) or
something of that sort. (Anyone notice that the duels mostly consist
of red and green flashes? Everyone's casting AKs or Stunners? Where is
their imagination?) 

I used to imagine a spell named in honor of Evan Rosier which caused
roses to bloom all over the victim's face, thorns and all. Or how
about "Umbridgitis!" which would turn the victim into a toad, warts
and all. Or how about one that Transfigures the victim into a chair,
named after Horace Slughorn? That would pretty much eliminate their
ability to fight back. These spells would not necessarily be
permanent, but they would be complex enough not to repond to "Finite
Incantatem." They would need to be reversed by a specific counterspell
known by their inventor (and possibly his or her friends).

Carol, who is juat having fun here but did think that the Baby-Headed
Death Eater was more effectively dealt with, albeit accidentally, than
those who were Stunned or Petrified
