"Ciel, now just grab the blade and swing it at the damned horseman! If he doesn't go down in one hit, swing it again. I don't care, but keep swinging it until there is no horse or horseman left to take damage!" commanded Illya, kneeling as she grabbed her left wrist to stop the bleeding, as golden threads flickered around her hand, and other wounds.

Of course Illya's magicka regenerated enough for her to start healing herself, although this would probably deplete her magicka again. As for why Illya didn't fuse her blood into a sword before ... she didn't have transmutation ability.
