Any level up tips for dancers?

I use Azama with his pain attack that deals 10 true damage and a dagger character like saizo for chip damage and Narcian for savage blow. That should leave them easy pickings for any character

The game changed for me after getting Sakura for training.

If shes at level 20, and you are struggling, use a healer with pain, so that way they can drop enemy units to low hp for Ninian to finish off, you can use a second dancer to just reanimate the healer for max healing or hp reducing. Keep the 4th slot for someone to get rid of high priority targets that Ninian cant combat.

Also since she is blue (Atk x 1.5 x .8), i think if she has enough speed she will survive the falchion attack, I'm more worried about Julia, and breaker skills take up slot B, I rather use Vantage with Lightning Breath+ for defensive kills or Escape Route to run away and possibly dance up another unit (I'm not too familiar with how Wings of Mercy and Escape Route works yet...)

Honestly I haven't used Ninian yet, so I can't say how much that -spd is detrimental, so try these out and see how they do, you can always merge them into another Ninian when the new patch comes out with skill merging.

Hope that helps. ^ ^

20 to 40 lving up. Use a healer like sakura, and you can bring olivia that way you have double heal and +4 att +4 res, the 4 slot bring a powerhouse...

for the inheritance... I use HP+5, with HP nature she will have 50 HP, Julia attack you with 70+ so dont bring close to her. 50HP with escape route 3 give you a very good advantage she get a hit she survive, use X unit for move or attack, telenext to that unit and done she is at safe distance.

For especial, you can use
Sacred Cowl or Escutcheon. The main focus is to survive.

So...
A. HP+5, Fury3 or Svalinn Shield (if you wait until friday the new grand hero battle give you iote shield... it do the same that svail shield)
B. Escape Route
C. Hone Spd,Atk,Def... if you have other dragons keep her natural skill.
