The presence of resist or HP steroids built into your champion's kit, such as in Leona's Eclipse or Cho'Gath's Feast.Whether or not the enemy is capable of delivering true damage or percent health damage, thus reducing the value of armor and health stacking respectively.Percentage armor reduction in the enemy team tilts the optimal health:armor ratio slightly in the favor of HP.Against a team with mainly burst or just low magic damage, HP can be more efficient than MR. HP helps you survive both magic damage and physical damage.Unlike HP, increasing armor also makes healing more effective because it takes more effort to remove the unit's HP than it does to restore it.There are many other factors which can effect whether you should buy more armor or health, such as these key examples: The more equal the distribution of physical damage/magic damage in the enemy team, the more effective will buying health be. You can also see that for a somewhat brief period in the early game health is the most gold efficient purchase, however this assumes the enemy team will only have one type of damage. The equilibrium line represents the point at which your champion will have the highest effective health against that damage type, while the smaller lines represent the baseline progression for each kind of champion from level 1-18 without items. It can be helpful to understand the equilibrium between maximum health and armor, which is represented in the graph on the right. While for magic resistance the line is a bit shifted down and less steep: As of season six, the base equilibrium line for armor is a function: Note: The following information similarly applies to magic resistance. Turbocharged Hexperiment Turbocharged Hexperiment Reliquary of the Golden Dawn Reliquary of the Golden Dawn Locket of the Iron Solari Locket of the Iron Solari This table is automatically generated based on the data from Module:ItemData/data. By building armor items, you can receive more benefit and power from these abilities.

These use the champion's armor to increase the magnitude of the ability. 33%) of its maximum health as effective health. This is because negative armor cannot reduce effective health to less than 50% of actual health. When a unit's armor is negative due to armor reduction debuffs, armor has increasing returns with respect to itself. Armor can, however, give increasing returns if a unit has a source of flat post-mitigation damage reduction such as Warden's Mail or Amumu's Tantrum. This would mean that armor gives constant returns. This is not changed by any amount of armor already held. Each additional point of armor increases the effective health pool (against physical damage) by 1% of your maximum health. If the unit had 1000 maximum health it would take 1600 physical damage to kill it.īy definition, armor does not give diminishing returns of effective health. The damage calculation then uses the effective armor values after the reduction the actual damage formulae are not changed.Īrmor penetration, Lethality and armor reduction can be treated as negative armor in damage calculations.įollowing the above damage formula, each point of armor increases the effective health pool against physical damage by 1%, formally:Įxample: A unit with 60 armor has 60% increased health against physical attacks.

Armor has a gold value of 20 per point.Īrmor can be negated by armor penetration, armor reduction, and Lethality.

Total damage reduction 66.66%, + 200% effective health, 1,000 post-mitigation damage = 3,000 Raw Damage.

Total damage reduction 50%, + 100% effective health, 1,000 post-mitigation damage = 2,000 Raw Damage.Total damage reduction 20%, + 25% effective health, 1,000 post-mitigation damage = 1,250 Raw Damage.Post Mitigation Damage = Raw Damage ÷ (1 + ( Armor ÷ 100)) To determine how much damage will be dealt using raw and a given armor value we can use this formula: Solving the above formula for raw damage r gives For all non-negative resistance values this means using:

The formula to calculate post-mitigation physical damage based on raw physical damage received:ĭue to the order of operations for penetration and reductions of either resistance, negative values almost never occur.
