add 3 ashtals stones in your gloves too and you have less mana problems
Btw you need a better neck ^^
Ah and 1 ashtal in culet too, and try to get some good HH weapons with ashtals in only ( I prefer crit, dmg, ar and ele attack ).
With ranger buffs, lens, combi pots you can kill the mobs faster ( get with ranger buffs 198% cast and over 90% CD so
)
I tried to kill the mobs also with HH scion weapons only selfbuffed 8k ele dmg with hunter buffs over 12k, nice zerk buffs a little bit more but really less hp and mana
