Skill priority

You will level up most skills regardless how useful they are for the combat power padding in endgame. As a general rule of thumb:

Units you are not sure you will use long term: Skills to level 4. If they're passives that benefit the team, can take that to 10.
Strong units but not your main personality: Skills to level 10 for raids and elemental content. Not worth going higher if they are not your main team.
Strong units on your main personality (and waifus): Max out skills. You can start with 10/10/10 and slowly work towards 12/12/12 when you can sweep higher stages.
What about Yearnings? They unlock skills up to level 15. SUPER EXPENSIVE, only worth for your main team or really meta characters.

Recommended artifacts

Artifacts and runes will always change depending on the stage and content you are currently facing, this is just a couple of examples on what items work for this Apostle.
