Damage returned% is seriously crippled in PVP
1/6 PVP penalty from opponent
Any damage reduction you have
1/10 damage return penalty
1/6 PVP penalty (I think)
Any damage reduction your opponent has
No, it goes through the pvp reduction a second time, as it's an attack by based on an attack of your enemy. BTW, 1/10 of 1050 is 105, not 150 :azn:.
