Where to grind?

Hi. I've just got my G10 char on Hungames and I'd like to know which is the best place to grind. I went on 3 SoS maps and I'm getting nothing.

Sky Temple Exterior(Tier 3)

Grind on Hell Hounds at G10 then Demon Lords at G11
They do a lot of damage so you might have to buy a lot of pills and put your auto pill at 80%.

By the way, how do i level up at g5 ? i go to fairy palace D5- d8 and i get raped... i've got the rare d4 gear with 70 - 90%
