duster vs thorns

Wind lashed out in a column five feet around and drove into the wall of thorns. The thorns shuddered and then began to give, bending away from Elaine's spell.
"Go!" she gasped. "Go, hurry!"
I ran.
The wind almost blinded me, and I had to run crouched down, hoping that none of my exposed skin would brush against any thorns. I felt one sharp tug along my jacket, but it didn't pierce the leather. Elaine didn't let me down. After a few seconds, I burst through the wall and came out in the clear on top of the hill of the Stone Table.
