Damage is any means to reduce players' or units' current health.
Player damage[ | ]
Player damage is the damage dealt to players who lose a round to another player in Standard and Duos modes. Player damage is dealt according to the surviving Heroes, surviving Underlord and round number. Surviving Underlords deal 1 damage before round 30 and 2 after. Round damage starts at 0 and increases by 1 every tenth round. Summons do not deal damage to players.
Damage dealt by Heroes uses the following formula: 1 + (power level / 3)
A Hero's power level is:
hero: tier
hero: tier + 2- hero: tier + 4
