I forgot about Bloodman using IDS magic.

But then again, franmalth's Curse power allowed Franmalth to absorb and re-use Magic. Could be bloodman had access to franmalth's curse and used it to absorb some of Silver's magic. Granted, it would be foolish to not use Franmalth's Curse to beat Gajeel who is mostly a brawler.

Then there is the fact that Bloodman had some magic in him, as stated by others before me.
