[Hole Quest]

The goblins begin flailing about, rolling around on the ground and yelling!

"Bugger me! I didn't tink knuckers could breath fire!" owl-eyes howls.

They can't, of course.

But Isaac's illusionary fire isn't made of gossamer, so the goblins are quite a bit less likely to notice since it isn't their sort of illusion.

Silly goblins.

The bound children, should they get any of the imagined fire on them, don't notice at all.

Because they can't see it, therefore it isn't.
