Vestia?

I'm not good with builds so I'm not entirely sure what to do with her

I searched and found a really old build, but because of her buffs, it's a bit outdated.

Could anyone give me some advice?

2 force, go full tec. Well that's my plan so far owob

Force+force the AM, 3rd tune is preference, I go HS. Attach banish striker on her, go full tec or 20-20 are both fine.

This remind me I got another one with thx ticket, may be i should try 20-20 build.

I dunno about a 20/20 build since the whip isn't that combo extensive for the benefits of 20 str, but palm strike is cool stuff to setup a kill for you team or some sort of disable with draw-mech+tackle palm. But with 20/20, surely we can slot more hp, eternal tune, and revenge tune..

Depends, how do you want to play her?

I'm definitely going to be focused on the gun. I'm not the melee type, although I've been trying to improve recently on an alt

her capa is insane after her unneeded capa buff. You'll probably end up having the whip just for slots.

here is a video of pre-buff, no whip play. Shows bind ball and palm strike. Tunes are force+force+grapid. After the ammo buff and capa buff, you can probably get away with hforce+grapid+third tune. I don't think any speed less than grapid is worth it. Shooter, or even hshooter might be nice for more range, hers is kind of low. Hforce+2xhshooter probably isn't even that far out with her increased capacity.

here's a shorter, more recent video(still before buff) that shows some of her anti-melee abilities with force palm.

Even with low str, force palm has a forced catch mechanism and grants super armor, and pushes away to set up for a bind ball. Whip, even at low str, seems to stun regardless even with single hits.

Should be easy to do 40tec/36walk. She has a lot of nice carts - all 3 hop carts, fast recovery, moving burst, broad radar. She starts with assault step now so you can do something with that if you want. There's a lot to be done with the extra capa and you'll run out of carts to take.
