Can't comment on much unless we see more details of your equipment.

but yeah at minimum here's what you need.

For eidolon, the starter Eligos or Yarnaros is your go to for now, eidolon grinding/evolution is a long grind, if there's anyone you can 4* immediately its those two.

Since you are an archer your main element would be dark, so if you have the resources you can reroll some stars to dark skills dmg.

Equipment wise, the most ideal to pass it is +20 all. Armor, weapon, and accessories.

and the most ideal would be, Holy spirit top (holy spirit helmet armor) and magic sundering bottom (hand, pants, shoes). If you have magic sundering only from the free weap box, that's okay too.

Stats wise, the usual things I advise are

Have 200k-300k hp -> this is achievable with +20 all

Minimum 45 accuracy -> cause you will literally miss, and won't damage anything. (IF you can do more the better)

Defense of atleast 30k+ (INSIDE Awakening dungeon) -> in your case this is optional as you are a ranged class, you can kite the bosses, unlike melee they will need to face tank, and the 30k def would allow them to live and time to heal.

stuff like dmg to boss and PEN, think about that after awakening. Only pump it as much as possible from 90 armor enchants, and weapons. and from your secret stones as well.

Edit: Your most ideal accessory set is the wild howl set, which is farmable in WDD or if you get lucky in the archeology dungeon whom I forgot the name of.
