Sweeping both arms forward, you hurl the sticky strands of a web at the child!
Your web lands solidly on the child, entangling his limbs!
The child's wings become entangled, and he drops heavily to the ground!
Your sudden fall EVISCERATES the child!
The child is gushing blood.

Your punch injures the child.
The child's slap misses you.
The child is gushing blood.

c 'dispel magic'
The magic of the adhesive web spell is unaffected.
The magic of the faerie fire spell is unaffected.
The magic of the earthbind spell unravels.
You have become better at dispel magic!
Your punch wounds the child.
The child's slap misses you.
The child is writhing in agony.

I thought earthbind wasn't supposed to be dispellable at all, so I guess a physically caused earthbinding shouldn't be either?
