Where did the slugs that afflicted Ron come from when he was under the slug vomiting charm? Does the charm create life, or were the slugs plucked from somewhere else and placed inside Ron?

  • Pure speculation, but perhaps they only exist for a short time? cf. the bird charm Hermione uses on Ron in Half-Blood Prince.

    @alexwlchan - Hermione didn't use the bird charm "on Ron" per se. She used "Avis" to conjure the birds without Ron there, and THEN used "oppugno" to sick them on Ron Commented Sep 14, 2013 at 23:49

    I agree. Call this one a dupe. I VTC awhile back. You guys need to close it. Commented Dec 17, 2014 at 23:23

This seems a common thing in HP spells - Avis was used to conjure birds by Hermione and Ollivander, they transfigured inanimate objects into animate - see full list on the Wikia, Bat Bogey Hex was used to create bats from snot etc...

Also, spells were used to conjure/create flora - e.g. flowers to put on Harry's parents grave conjured by Hermione.

The canon was never very clear on whether this was life creation permanently, life creation temporarily, or transporting existing life from someplace else.

  • Alrighty then. The green check mark is now on hold. Commented Sep 15, 2013 at 1:32
