Tiers

Tiers are indicators of a given player’s killstreak (current amount of kills without dying). 
Reaching a new tier will give you a bonus amount of Spirits equal to your new tier level. 
Killing a player with a tier will drop a corresponding tier loot chest. Higher tier chests contain better loot. For example, if you kill a tier 4 player, they will drop a tier 4 loot chest.
