When you start the game with lots of Tears or Rods. Having an early start of Sorcerers also helps transition, but is not necessary.
Level up on 2 if you are strong and want to start a win streak.
Level up to 5 after the carousel on Round 4 if you want to continue your win streak.
If you were 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 to find at least Syndra 2.
7 After raptors, level to 8 if you haven't already and roll down to complete your team. Don't over roll, as you want to hit level 9 as soon as possible to transition into 6 Star Guardians.
This comp runs cheaper units at level 8 like Xin Zhao and Jarvan to try and eco to level 9. At level 9, you can drop Jarvan and Xin to add in Janna, Soraka, and Lulu. This will give you 6 Star Guardians, Mystic, and maintain Celestial.
Syndra will be a core carry in the mid game, so you can roll at level 7 to ensure you find her. After that, try to be as strong as possible while ensuring you can hit level 9.
