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.
Reduce the Cooldown of Charge by 2.5s for every 1000 damage your Shield takes.
Heal for 200 for each enemy hit with Fireball.
Reduce the Cooldown of Charge by 0.6s after hitting an enemy with Fireball.
Heal for 360 every 1s while Shield is active and you are at or below 35% Health.
Gain a 450-Health Shield for 3s after you use Charge.
Your Shield now uses a resource that Regenerates over time instead of using a Cooldown.
