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 - Hitting an enemy with a Basic Attack restores 1.4% of your Health, 2% of your Mana and reduces your active non-Ultimate Cooldowns by 0.33s. Basic Attacks that deal damage in an AoE restore less health (75% for Melee Attacks, 50% for Ranged Attacks) for each enemy hit after the first and only count once for the Cooldown reduction effect.
PASSIVE - You gain Physical Power equal to 2% of your Maximum Mana.
PASSIVE - Enemies hit by your Critical Strikes have 40% reduced healing for 5s.
PASSIVE - When your Ultimate ability has finished casting, your next ability or basic attack within 8s that damages an enemy god marks them, increasing the chance you and your allies can land a Critical Strike by 20% for 10 seconds. This can only occur once every 45 seconds.
PASSIVE - Your Critical Hits provide you with 10% Physical Penetration for 4s.
PASSIVE - Your Basic Attacks benefit from an additional 20% Physical Penetration.
