Katalina BG NEXT questions

Well I just got her with UC -> Rt and she's the only gold ball i have so i wanna use her to full potential
My questions:
1/ How should I use her? (Moving Burst, holding bucklers and shoot the internals or what?)
2/ Should I keep her AMs?
3/ What weapon to hold?

Thanks ~

I don't usually support corespamming builds but that's probably the best route to go with NEXT. So all the usual core-only stuff applies.

I'd suggest getting Float Dash, both EIW, and dropping her AM's for something such as Crimrose AM(to keep looking moe) , Tentrion AM, or Machknight AM.

BS's are up to you but I prefer Sword Wing BS. I'm not sure of her stats but I think there's probably better BS choices.

Thank you mates you guys help me a lot OwO Still I'm wondering should I tune for TEC or TGH after getting 38 fly and do I need any side weapons?

You should have room for 40 tec 38 fly with room left over for HP and/or tgh.

Side weapons are up to you, I'd consider a <20 cost gun or a shotgun/blaster of some sort. Her core's probably good enough for air-to-air thanks to massive boost drain.

My current build is 36tec-38fly-16tgh, 5x capa, 2EIW, stun regain, float dash and broad radar.
Using one handy mag and one buckle, thought i'm planning dual buckle since ammo is not really problem.

Wow you guys are really a big help. I can survive in arena with Katalina now.
Just some thoughts slipped my mind. Is abbandoning TEC and go for TGH to make her a flying brick a good idea? I think her core's force is high so why not aim for more survival ability?

Stick with Tec. It does good damage but is low on ammo. Better take advantage of its power.
