The Arrow Deflect passive sub-skill provides a chance to both deflect an arrow, and cause said arrow to ricochet back and hit your attacker. The chance to cause an arrow to be flung back at your attacker is much lower than that of a normal deflect.
When this sub-skill unlocks at level 200 (20 standard), it only has one rank but the chance to deflect continues to increase every 100 (10 normal) levels.
