There are two types of seaon result rewards which can be acquired at the end of every season.

▶ Completion rewards: Participating in five matches after reaching a certain tier
▶ Result rewards: Rewards depend on the tiers when the season ends

For 'Result rewards' you will receive the rewards depending on your highest tier from your Classic(TPP/FPP) solo, duo and squad modes.

For example, if your tier has been dropped from Conqueror to Ace,
you still can receive the Conqueror crate.
