Celtic Heroes

My stats are below and this build is what I was using up to 200, if I could make any improvements it would be appreciated, my gear which you may not be able to make out is:
Dark sun mord helm (1k hp and energy and 100 heat dmg), royal dmg/cun/def brace and royal cun/atk/def brace along with 3 runic valour rings
My skills are:
Ss 40/40
Qs 45/40
Sneaky atk 45/40
Lifesteal 40/40
Riposte 40/40
Rest in expos for bosses
I will be thankful for any advice given.

Nice gear wouldn't double attack be better for you instead of lifesteal?

your set on hp for life, life steal may not be needed, swap with double attack imo

Level up to 215+

Switch dex and str, get a frost set, spec max smoke, expose and poison along with ss and qs and become a support rogue.
