From the above sheet we can see the rolling system of Team Fight Tactics. The more high level you get the more chances high Tier champion would come out. On the other hand, it is more difficult to get a low Tier champion at high level.
- The best chances to get a Tier 1 champion are before level 5.
- Tier 5 champion are available after reaching level 6.
- The more money you get the higher interest you can redivide, but you may miss the best chances to get the low Tier champion.
- The buy and selling cost of every single champion are the same, you may buy all 5 champion after rolling for strategic use and sell them later.
