had been cast upon it. giant vermin A later version could be reused once a day, with the insect being summoned and vanishing after one minute.

giant bee, giant praying mantis, giant queen ant, Giant stag beetle, giant wasp, huge monstrous centipede, large monstrous scorpion or large monstrous spider.
