Need help with future investment

Finally got a reroll with ray + yeli. I still has beginner banners and boxes. How do I plan like what should I get from selection banner and boxes? For PVE only purpose

Should I skill up yeli or ray first?

[static spire]

i would say use yeli as ur solo dps

455 yeli first

then lily 511

then plume 413

use 3 of them as ur pve core

u can use ray as sub dps 155 work

then have 1 sp per content

terror: maybe val

doki: green kazu

aurora: a healer (maybe linglou or red chiaki)
