This is a list that beginners must do to not take the wrong step in the game
Perform the main quest to unlock several features such as awakening black spirit, camp buildings. if you cannot continue main quest anymore or it's too difficult to kill monsters in the dungeon, then follow a few suggestions from me.

1make sub characters with the same job as your main character and then do the main quest again, what benefits can you get from making sub characters? You will get a boss stamp, ancient tablet, stone, silver, and contribution points.
2.if you get a drop from a dungeon with a grade below yellow give it to your black spirit to add the black spirit's Lv to increase your CP(accessories with blue grade and above only sell in the market)
3.I think you will experience difficulties starting from West Calpheon or level 50 onwards you will often experience stuck CP and at that level it is the transition from the purple equip to the yellow equip, it is better if you save your silver to buy a equip liverto set compared to buying another yellow equip grade.

4. Run boss rush and ancient ruins to get shakatu coin,exp,and silver. you can use shakatu coin to try your luck at shakatu shop, even if you don't get the items you want at least the equipment that you get from shakatu shop can be given to black spirit.
5.Fuse lightstone and relic stone . No description about this you just to fuse and try yourluck.
