A large colt with tusks asks if the spiders can heat the bronze; before Volterra can oblige and use his limited control over the creatures to send them towards the bronze, all hell breaks loose. Out of the corner of his eye he notices his son suddenly shift into a blue jay, and this display of magic would ordinarily have the man's whole attention; as it is, his focus is very much on the swarm of ants that have decided to attack their assailants, and the cowardly spiders who have upped and left them to it.
He glowers at the arachnids, before his own legs are suddenly lost beneath a moving throng of ants. They climb high and bite through his flesh, causing the stallion to roar and stomp his forehooves with the force of a wrecking ball. Tiny little pinpricks delve through his skin, a canvas of different pains that irritates the leviathan beyond belief. Astarot's bird-voice reaches his ears and his eyes widen at the idea; yes, the ants hadn't liked the heat, so it may work!
It takes every ounce of the beast's concentration as he summons his magic again. He has created large creatures before, but never this many small ones, and the toll on his strength is instantaneous as the ground nearby erupts with about a dozen small fire-spider golems. He instructs a couple of them to scuttle towards him so he can reach down and grab them, then swing them unceremoniously around to try and burn the ants off him.
Although Volterra is not an altruistic man by nature, it seems rather rude to not offer his golems' services to others. So he uses his mind to force the fire-spiders towards every other person that has ants upon them, their stone legs clicking and their rocky pincers flapping menacingly as they advance on the copious amounts of ants. Hopefully their heat will cause them to move from their horse targets or at the very least cease their biting in their haste to flee, whilst also offering the option for the others in the clearing to use them as weapons as Volterra is.
Meanwhile, the spider that Astarot is trying to entice goes willingly towards him, allowing itself to be flung towards the anthill in a shower of stone and flame.
