Of course when I use frightening aspect i can clearly see my hp go back up, now here comes the setup. you need 5%+ life steal, 4.2 + defense , 700 AR and i believe my ring called litany ( 7% less damage from elites ) make a difference. I don't use jungle fortitude but with that passive im guessing you would need less defense and all resists and maybe a bit less life steal, I haven't tried.. I'M just stating here what I have and I have no problem at all vs reflect on mp10, I do mp10 really easy.
This is not a show off thread but clearly to show that reflect damage can be taken care of fairly easy it a mix of some piece of gear. Some will say " its lame to gear only for 1 affix " ( brahm ) :) But imagine how EASY i can do mp10 if I am able to face reflect damage monsters that easy.. it's making your whole mp-8-10 easier by making your character less glass cannon.
Pretty much the key parts are a skorn with 5% + life steal / litany ring with 7% reduced damage from elite ( assuming it works with reflects ) 4k+ defense ( easy to get ) 700 all resists ( easy to get aswell ).
Those parts aren't that expensive unless you get the best of each. You can make it even more easier by using jungle fortitude but I rather use all three mana passive and spam bears pretty much non stop.
