Teamfight Tactics players are often faced with the choice between fishing for low-cost units and leveling up.

Spending your resources on developing units and taking control of the board is sometimes the best course of action. But deciding when to level and when to roll isn’t straightforward. Without the numbers, it’s pure guesswork.

Thankfully, Riot has released a chart detailing everything we need to know about champion drop rates by tier and level.
