What should my last upgrade skill be?

[Mangafan2]

I got
vit mastery lvl10
ruling force lvl3
force control lvl8
reflex lvl9
sixth sense lvl3
(they are all upgraded to the max)

so what should my last one be?
I thought of damage absorb, but I just need some confirmation of the pro's on this board here :)

Thanks in advance!

Well, yeah, Damage Absorb is a must-have, as it gives us a lot of defense (and there isn't anything else good once you've got the others).
