This is our proprietary skill rating calculation. This has nothing to do with official game ranking or MMR.
The purpose is to show player skill levels relative to other players, not estimate MMR.
Your non-ultimate ability cooldowns are reduced by 0.5s every 0.5s for the next 3s. Shard Relics can be upgraded to a new Relic once you reach Level 12. Cooldown - 120s.
