Level up on 2 if you are strong and want to start a win streak. Level up to 5 after carousel on 4 if you want to continue your win streak.
If you are lose streaking up to round 7, you can level up to 5 if you don't think you can beat the creeps.
Level up to 6 if you are on a win streak during Round 2 or level up to 5 if you haven't yet.
Win streak or lose streak, you should normally catch up to level 6 on Round 2. Roll a small amount if you are very weak and need to stabilize.
Before the fight on Round 1, level up to 7 and roll down if necessary.
7 After raptors, level to 8 if you haven't already and roll down to complete your team.
2 frontline and 2 backline as usual is a great start.
If you have 4 Dark Stars, you will spike in terms of damage, but you may be lacking frontline if your Jarvan has no items. You can also run 4 Protectors alongside Jhin and Ashe if you feel your frontline is too weak.
Jhin, Shaco, and Xerath are all strong carries for this team. Jhin and Ashe are core, but Shaco can also be a carry alongside a unit like Fizz or Ekko. Similarly, Xerath can be another carry if you have extra items and find him 2 star.
We recommend a defensive item on Jhin as with Dark Stars, reviving as the last unit can be a lot of potential damage. However, if you are confident in your positioning, you can run 3 offensive items instead.
