Congrats! Auto-egg is on right now, so you’re good there. If not, you can shout to see if someone can egg you. If all else fails, your Sadad skill Barrier is just as good as an egg if you add base spirit; barrier defense increases at 1% increments every 200 base spirit up to the max (at 5000+ base spirit).
If sky maps are too hard, you can try SV (Signus Valley), which is accessible in the northeast corner of BX. Experiment with switching out your Nova Blade for a Chrysaor. When you think you can afford to spend some tokens on sunsets, a Manus Blade and some sunset armors will help quite a bit for survivability, hit rate, and attack.
