where do you intend to use her?

scarab, with klod

faction wars

any place where my team is dying

If  you  have  the  gear  she  can  be  put  in  a  Shield  set.  All  you  really  want  on  her  rught  now  is  Defense,  HP,  and  Speed  so  if  you  get  up  to  good  amounts  of  those  stats  with  a  Shield  set  then  do  it.

I can get good defence and hp, the best possible for me, but not on speed, unless I get reasly lucky rolls. I guess imortal can do much less, since I have better sheild sets. Forgot two mention, she's paired with Elhain for 3 starring campaign.

If  you  don't  have  the  best  gear  go  for  stats  not  sets.

then sheild set. No doubt, my immortal sets are just awful. Melga will be slow unfortunately, but don't really have good boots

To  get  high  enough  speed  and  HP  you  don't  necessarily need  a  Shield  set-  don't  focus  on  trying  to  form  a  set-  focus  on  trying  to  push  your  stats.

then don't use a set bonus, like destroyer said. having an extra 40-45 speed on melga is much better than having her apply a shield set or boosting her hp. for now, the most important thing is to make sure she has the ideal stat on her equipment (hp%/hp%/spd) and then work toward getting set bonuses as you aquire more gear.

now assuming you have good gear in all the sets you mentioned, i would recommend 3x life or immortal gear, or 2x and a speed set if you want her a bit faster. regeneration gear isn't useful enough to be worth using imo (and even in the rare case where it might be, it's still usually better to use guardian gear) and while shield gear is pretty useful, the fact that it only has an effect for 3 turns makes it less useful in drawn-out battles, which both scarab and faction wars entail. i'd also focus heavily on hp over defense rather than a more balanced spread, both because it improves a1 and a2 and because dwarves have the boss that ignores defense as their floor 21 boss.

Good advice here, but I might go mix of hp/def (really whichever u have that is good) as stated multiple times in this thread and elsewhere:

STATS > SETS (to which u replied, "ok a sheild set" lol)

The ignore defense of the FW21 boss is a b!tch, but I think that is a non-issue for the OP

oof, misread the post. And my speeds would be aroud 140 at speed boot+health. really struggling with speed 😭
