League of Legends Resistance & EHP Calculator

What Exactly is This "Effective Health" Sorcery in LoL?

You've felt it: that important teamfight where you almost made it out, that gank you nearly turned around. What if the secret to flipping those near misses was just about understanding your champion's true tankiness?

Forget just stacking health, that's just the tip of the iceberg. It's time to talk Effective Health (EHP), and here at igitems, we're handing you the key to unlock it with our state-of-the-art League of Legends Effective Health and Resistance Calculator.

So, what's this EHP everyone's whispering about? Think of your champion's health bar as the visible tip of the iceberg. Effective Health is the whole iceberg. It's basically the total sum of raw damage your champion can actually withstand before heading to the grey screen.

As the strategy puts it, EHP gives you a far more accurate measure of your tankiness than your health bar alone, and more EHP means you laugh in the face of burst damage and shrug off sustained damage.

How EHP is Calculated in League of Legends

While our calculator does the heavy lifting, understanding the core principle is neat. The fundamental idea is: EHP = HP * (100 + Resistance) / 100 For instance, if your champion boasts 1000 HP and has 100 armor, your EHP against physical damage isn't just 1000; it's a beefy 2000. That's because 100 armor effectively halves incoming physical damage. The same logic applies to magic resistance against magic damage.

Factors That Define Your EHP

Truly understanding EHP in League of Legends requires a pretty keen eye for a few in-game details. Let's go through them:

Health vs. Resistance

Ah, the age-old question: Do you stack more bonus health with items like Ruby Crystal, or boost your defenses with cloth armor and null-magic mantles? Well, the truth is, both health and resistance contribute linearly to your EHP, meaning there isn't a magic breaking point as such.

Instead, the optimal item balance shifts based on your current stats, the enemy team comp, and what your champion's abilities scale with. That being said, most commonly, in the early game, a mix might be fine, but as the enemy team picks up penetration items or stacks defensive items, your optimal build pattern will have to adjust.

Magical, Physical, and True Damage

In League of Legends, not all damage is created equal, and your EHP varies depending on the type of damage being dished out by the enemy team:

• Physical Damage: Mitigated by armor, think auto-attacks from AD carries or abilities from AD assassins like Zed.
• Magical Damage: Reduced by magic resistance, this is the calling card of mages and champions with ability power scaling.
• True Damage: True damage, like Vayne's Silver Bolts or Olaf's Reckless Swing, bypasses your armor and magic resistance entirely, hitting your raw health pool directly.

As you can see, understanding the enemy's source of damage is paramount. For example, stacking armor against a team of five mages? That's a fast track to loseville, yet sometimes we see it in our games.

Understanding Armor and Magic Penetration

When you think you're an unkillable titan full of tank items, along comes armor and magic penetration. This is how enemy champions slice through your carefully constructed defenses, and it comes in several flavors:

• Lethality and Flat Magic Penetration: These stats, found on items like Duskblade or Sorcerer's Shoes, reduce your armor or magic resistance by a flat amount before damage calculation, which is great against squishier targets with lower base resistances.
• Percentage Armor and Magic Penetration: Items like Lord Dominik's Regards or Void Staff reduce your resistances by a percentage. This is great against champions who have heavily invested in armor and magic resistance. For example, Black Cleaver can shred up to 30% of a target's armor when fully stacked.
