Goldolf armor is tough,

Rolonia's whip was able to catch Goldof multiple times. However, each time it  was blocked by his armor and could not reach any of his blood. But it wasn't the  durability of Goldof's armor that was frightening, it was his reactions. Rolonia was  accurately aiming for the gaps in Goldof's armor, but with his reactions Goldof  was able to move only slightly and still block them all.
