Foster stumbles midgallop. He staggers sideways, falling to his side and rolling--his broad bear shape helps a little, but the ice spears erupting from the ground do not.

Taako's quick thinking probably saves his life. One of the blades cuts open his side, his blood freezing briefly to its surface before he actually (accidentally) rips himself off of it in the process of regaining his feet. It leaves a bigger wound behind than the spike itself did.

But the most basic perk of a pact with a demon is access to fire. Hell fire, specifically. Digging his claws into the earth, his paws wreathed in it, flames leaking from his jaws, he throws himself forward into the blades themselves.

Hopefully, hellfire is strong enough to melt fae ice--or he's going to turn himself into a 900 pound bear kebab.
