Since I already have sewer king set, I have decided to make a bird L51. I also buying L51 str items.

I do not know which is better, full dex or str/dex.

and I also need to know which build would be best.
(is heal needed, must need both roots?)

the build I have in mind now is
6buffs 6blast 6shatter 6blind 6repulse 6break 1avain 6on the first root(unocked lvl6) and 1on the second root( unlocked L22)

another one is, without the second root but put on restore instead.

Please tell me what should i use. and also the stat points. If possible, gear infos would help

Your help is much appreciated.
