From reflect enchantments, it doesnt seems to absorb damage. You will still take damage, but reflect base on the percentage you take. Let say you taking 80 damage, if your reflect only 20%, that 16 damage being bounced back to that particular mob, make it taking 16 more damage. And chances of reflect also base on percentage. I didnt bother much on this skill, so no idea how high the percentage can reach with high skill ranks. Beside that when mobs doing literally close to no or pathetic damage on my toon, this skill doesnt seem very attractive.
