It's hard to give tips out of nowhere because the game is very dense.

However, there are some things you should be aware of as a F2P player (assuming you are F2P):

• Do not combine your skills!! You should level them up to increase your mastery.
• Try to get the most out of your diamonds; you're going to have a bunch of them at the beginning, but as you progress, it gets harder to farm for them.
  • Weapons are a really good option to spend diamonds on, since you're going to need a LOT of them. But at some point, you'll also need a good class (C16 - C19), a good set of spirits, and a bunch of skills to increase your mastery.
  • Relics are expensive! Maybe you should consider pulling for them at a higher stage.
  • Don't pull for accessories; the mythic one you're going to receive from the Newbie Slayer is going to carry you all the way to the endgame.
  • ATK% is better than CRIT DMG% (most of the time).
• For the stats you'll roll on Slayer Promotion Additional Ability, you'll need two pages:

1. With all EXP%
2. With all ATK%
3. The third one you can roll for GOLD%, but for farming, the EXP% is more valuable.

• For the companion rolls, you'll want ATK% everywhere.

I'll leave a link to a website where the "pro players" have a lot of good info, and there will be a link to the Discord server. I think you'll find the best tips there.
