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.
PASSIVE - For each enemy God within 55 units of you, you gain a stack of 4% Damage Mitigation. This caps at 3 stacks.
AURA - ALL enemies within 25 units are dealt 20 (+1.5 Per Level) Magical Damage per second.
