Morkilus made a good point. He meant Thaumaturgy, though, not Transmutation. The astral site-searching spell, Arcane Probing, is Evocation, and Death and some odd underwater site-searching spells are in Conjuration.

EDIT:
It might be that your arrow hit the Manticore, perhaps even to the heart. However, it wasn't necessarily enough to kill the beast. He will boast a chest wound, though. Most human heroes die after an Arrow, though. Is there a cross (indicating Death) next to the hero's name in the list of heroes?
