If they do stack, how exactly do they stack? My best guess is that you'll have a 50% chance of reflecting 110% damage (Damage Return) and a 35% chance of reflecting 120% damage (Advanced Reflect). These are completely separate, but it is possible for both of them to activate if you are lucky. Is this correct?
Thanks in advance!
P.S. I would totally test this out myself if I didn't have to get to level 80 to do it.
