Actually, given that the collab advent event will still be running through this union event, once you've collected enough materials to limit break your hime a couple of times, go back to farming the advent. And don't forget to spend your BP on poking demons so you can pick up some enhance mats. You need to get stronger and climb up the difficulties until you can consistently clear ultimate. That's when one can really farm advents.
If you end up having materials leftover after both the raid gacha tickets and the weapon? You can skip the eidolon from this collab event. Get either half-elixirs, jewels, or the kamihime ticket (which will most likely be an R).
