AD:
Jo's been pretty good about showing us that botched magic can have
serious side effects--from Seamus' burnt feather, to Neville's melted
cauldrons, to the toilet that Harry shattered when he missed Draco
with a Leg-Locker.

Even a magical dud like Lockhart managed to collapse a stone ceiling
when his Obliviate backfired.  Why should we be surprised that the
misfire of a powerful wizard's AK was similarly destructive? 

Hmmmm... Hey Peter!  Want to pay off that Life Debt?  All you have to
do is swap his wand with this one.  Don't mind the spellotape.
