MINION DAMAGE BONUS : While your team has a level advantage, your minions deal bonus damage to enemy minions equal to 5% + 5% per turret advantage in their lane, all multiplied by your team's level advantage.
NERD ALERT : Bonus damage = (5% + (5% x Turret advantage)) x Team level advantage
•If you're ahead by 1 level and are up by 2 turrets in a lane, the minions in that lane get (5% + (5% x 2 turrets)) x 1 level = 15% bonus damage
•If you're ahead by 2.5 levels and are up by 1 turrets in a lane, minions in that lane get (5% + (5% x 1 turrets)) x 2.5 levels = 25% bonus damage
MINION DEFENSE BONUS : While your team has a level advantage, your minions take reduced damage from enemy minions equal to 1 + 1 per turret advantage in that lane, with the turret advantage bonus multiplied by the team's level advantage.
NERD ALERT : Damage reduction = 1 + (Level advantage * Turret advantage)
•If you're ahead by 1 level and are up by 2 turrets in a lane, the minions in that lane get (1 + (2 turrets x 1 level)) = 3 reduced damage
•If you're ahead by 2.5 levels and are up by 1 turrets in a lane, minions in that lane get (1 + (1 turrets x 2.5 levels)) = 3.5 reduced
