Ok awhile back I randomly got a Tana. I was just wanting to know some recommended builds for because she's +def -atk
+def actually makes her into a really strong physical tank thanks to the effect of her weapon. If you have close defense then you can fortify that effect even more, but fury will still be great. -atk is actually not the absolute worst, because her legendary weapon has a lot of might. Just use her as a physical bait/duelist.
Weapon: Vidofnir
Assist: Reposition
Special: Bonfire (recommended) / Ignis
A-Slot: Close Defence / Steady Stance / Fury
B-Slot: Quick-Reposte / Guard 3 / Vantage
C-Slot: Threaten / Flier Buff / Guidance
Sacred Seal: Deflect Magic / Deflect Melee (with Vantage) / Speed / Defence
There are probably a few more options I’m missing, but this should suffice as a general template for +Def Tana.
Edit: Armoured Blow, Steady Blow, and Sturdy Blow are actually interesting choices since they allow her to act as a duelist rather than bait unit.
