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 - Enemies hit by your Basic Attacks are burned, taking 16 Physical Damage (+7% of your Physical and Magical Power) over 2s and have their Attack Speed reduced by 4.5%. Gods take 50% damage. Jungle Monsters take 4x the amount of damage and restore 2.5% Health and 5% Mana when they die. This effect can stack up to 3 times. Can be upgraded at level 20.
PASSIVE - While below 60% Health, you gain an additional 15% Physical Lifesteal for 5 seconds. Can only occur once every 15 seconds.
PASSIVE - Your abilities heal you for 2.5% of damage dealt. Each time anything dies within 80 units you gain a stack. Gods, Large Jungle monsters and Bosses provide 5 stacks. At 100 Stacks Soul Eater Evolves, gaining 15 Physical Power, 4% Physical Lifesteal, and 10% Physical Ability Lifesteal.
PASSIVE - Successfully Hitting an Enemy God with a Critical Strike will subtract 3s from all of your abilities currently on Cooldown, except your Ultimate ability. This effect can only happen once every 5s.
