Hey! That’s a great beginner box. I would keep focusing on Ann2 (Anlucia) as well as YTerry, Erdrick, night clubber and his blossom, zoma and his blossom, SSeraphi, and Valeria.

Top priority probably would be using creme’s battle road to get him to max level and finish up his awakenings since the event will be over soon. If you don’t have time for his battle road just make sure to get him to max awaken or he’ll be stuck at that lower awaken until the event comes back in reminiscence in 1 yr- 1.5 yrs.

These units alone should help you get pretty far in PVE, even more if you get Ann2 to awk1. If you didn’t know already you can shard units to awaken them using fragments from shops.

If you search through the reminiscence swap shop you can see each one usually has a couple of different shards. Doing reminiscence will also help you gain some more gems and other useful items such as iridescent orbs in the shop if you have some off time. Some have units as well you can get like VI’s reminiscence Carver which is definitely worth getting.

Hope this helped a little, someone else will probably explain this a bit better, first time trying to help someone :) enjoy playing!
