For new player, just get Asula accessories set, it will gives +350HP as bonus for 3 set and +20 accuracy for 5 set

You can swap them with RCE/BCE/Witch for blue Earrings and leveling up your character to lvl 61 to get Capotia Ring,
and finish the Kamasylve main quest to get Grana Oath Earrings.

My recommendation is to have 3 set asula, Capotia ring and Grana Oath Earrings + Tri RCE/WITCH before you attempt to have yellow accessories and then you can try to get Basilik Belt or Ring of Crescent Guardian before attempting Layten/Ogre/Tungrad/Narc.

AND NEVER EVER ENCHANTING YELLOW ACCESSORIES BY YOURSELF

Just buy it off the market, its cheaper in term of cost and time saving. 
Unless...... you want to battle this RNGod,
Here what failstack number i used to get higher chance with minimal cost,
Use 20FS for Pri, 40FS for Duo and 60FS for Tri.

BONUS TIPS : YOU CAN CRAFT RCG/BASIL BY YOURSELF!
Go to Valencia City, talk to Ossa Dilla. (You need 30 Energy to gain Yona Knowledges)
You can get Yona Fragments by heating Valencia accessories.
RCG/Cadry will give 3-5 fragments.
Serap/Sicil will give 3-5 fragments.
Basil/Centa will give 5-7 fragments.

Purchase Jeweler in Altinova 4-5 (need 10cp for this)  to craft Basil/RCG.
(refer to jeweler house to know what other materials also needed)

You can get RCG/Basil cheaper from current market prices.
