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 - Getting an assist when an enemy dies provides a stack that gives 1% Movement Speed and 2% Attack Speed for 8s to nearby allies up to 10 stacks. When you've gained 3 or more stacks from assists, once per ability, each time you damage an enemy god you restore 18 Health and Mana to nearby allies within 55 units and gain 10 gold. Can be upgraded at level 15.
PASSIVE - When your Ultimate ability has finished casting, you gain a Shield equal to 90% of your Protections from items and abilities for 5s. When destroyed, by timing out or being depleted, it explodes in a 30 unit radius and deals Magical damage equal to 75% of your Protections from items and abilities and slows targets by 25% for 3s. This can only occur once every 45 seconds.
PASSIVE - Every 8 seconds you gain a block stack if you have at least 80 total Protections from items and abilities, preventing 65% of the next Basic Attack's damage. For each additional 80 total Protections from items and abilities the max. stacks increases, up to a cap of 3.
PASSIVE - Physical Critical Strikes bonus damage taken is decreased by 40%.
