I'll try ice titans then.
And I play a vit sinx, not flee. So I have 20k hp, 190aspd and I think it's 100str.
If you're going vit sin depending on your equips and def you might be taking pretty high damage and using quite some pots x__x
I would advice going flee just for that moment lol. Seriously saves pots x__x
(of course, if you don't mind and can break even your profit then meh~ lol)
For me, I've never use pots there unless emergency when there's a huge mob.
(most of the time i just run away to break up the mob or tele, since their walking speed isn't that fast)
I just use a vitata clip to heal up if my hp is low lol. (yes!! its a pretty slow method x__X but it saves pots xD)
