Reflection and thorns

Assuming I have 100% reflection and thorns, does that mean that if I take a hit, the mob that hit me will take the same dmg?

 

Technically yes but you have to take into account that mob health values and player health values are different, so there is not nearly enough payoff for running thorns/reflection even at 100% to justify them being your primary build stats especially since you still take full damage when it procs. Aside from situational cases such as where there are tons of lower-health mobs that happen to deal a lot of damage, overall gameplay doesn't offer any situations where reflection or thorns are very useful (especially since they are two different stats you have to build for) particularly in higher-level content such as raids.

 

it actually deals 150% of the damage back to your enemy but 1.5 * 0 is still 0
