What Is Attack Rating in Elden Ring?

Attack Rating (AR) is the single most important number on any weapon in Elden Ring. It represents the total offensive power your weapon delivers before the game applies the enemy's defensive stats. The Elden Ring damage calculator on this page breaks AR into its three components — base damage, Strength scaling bonus, and Dexterity scaling bonus — so you can see exactly where every point of your damage comes from.

Base damage is fixed by the weapon itself (plus any upgrade level on a +0 through +25 or +0 through +10 somber scale). Scaling bonuses are variable: they depend on the weapon's scaling grade and your character's actual stat investment. A weapon with an S scaling grade in Strength will reward heavy stat investment far more than one graded D, which contributes only a modest bonus even at high stat values.

Understanding AR lets you compare weapons accurately. A weapon with 150 base damage and B-grade Strength scaling at 60 Strength can easily out-perform a weapon with 200 base damage but no scaling at all, once the scaling bonus is added in. The Elden Ring damage calculator does this arithmetic instantly so you can theory-craft builds without loading up the game.

Elden Ring inherits the AR framework from FromSoftware's Dark Souls lineage but introduces a broader weapon catalog, new scaling attributes like Arcane and Faith, and a more complex upgrade system. This calculator focuses on the core Strength/Dexterity interaction that governs the majority of standard and heavy infusion weapons.

Elden Ring Damage Formula Explained

The Elden Ring damage calculator uses the following sequence of formulas, matching the game's own hidden math step for step.

Step 1 — Effective Strength. When you two-hand a weapon, the game treats your Strength as 1.5× its actual value (floored to an integer). A character with 40 Strength effectively has 60 Strength while two-handing. This is crucial for Strength builds because it means you can meet the 60-Strength soft-cap for scaling without actually leveling to 60.

Step 2 — Scaling bonuses. Each attribute scaling bonus is calculated as:

scalingBonus = baseDamage × scalingMultiplier × (stat / 100)

The scaling multiplier converts the letter grade (S through E) into a numeric factor. The stat value is divided by 100 rather than being a raw lookup, which means scaling is linear with respect to stat investment in this simplified model — every additional point in Strength or Dexterity contributes proportionally to the bonus.

Step 3 — Total AR. totalAR = baseDamage + strScalingBonus + dexScalingBonus. If a counter hit is active the total is multiplied by 1.15; if a charged heavy attack is used the total is multiplied by 1.30. These multipliers stack multiplicatively if both apply at once.

Step 4 — Defense reduction. The game applies the enemy's flat defense stat using the formula defenseReduction = 100 / (enemyDefense + 100). Higher enemy defense values progressively reduce the fraction of AR that lands as damage, but the reduction is never total — there is always a positive damage floor.

Step 5 — Negation reduction. Damage negation is a percentage-based reduction applied after flat defense: negationReduction = 1 − (negation / 100). A 20% negation means 80% of the post-defense damage actually reaches the enemy's HP bar.

Final damage = totalAR × defenseReduction × negationReduction

Elden Ring Final Damage Formula

finalDamage = [baseDmg + (baseDmg × STRmult × effectiveSTR/100) + (baseDmg × DEXmult × DEX/100)] × [100 / (enemyDEF + 100)] × (1 − negation/100)

Where:

  • baseDmg= Weapon's base damage (before scaling)
  • STRmult= Scaling multiplier for STR grade: S=1.75, A=1.25, B=1.0, C=0.75, D=0.5, E=0.25
  • effectiveSTR= Strength stat × 1.5 (floored) if two-handing, otherwise raw Strength value
  • DEXmult= Scaling multiplier for DEX grade using same letter-to-number table
  • DEX= Character's Dexterity stat (1–99)
  • enemyDEF= Enemy flat defense stat for the damage type
  • negation= Enemy damage negation percentage (0–100)

Scaling Grades: S, A, B, C, D, E, and None

Every weapon in Elden Ring displays a letter grade beside each scaling attribute. These grades are not cosmetic — they directly control how much your stat investment amplifies the weapon's base damage through the scaling multiplier table below.

Grade Multiplier Bonus at 80 Stat (100 base)
S1.75+140
A1.25+100
B1.00+80
C0.75+60
D0.50+40
E0.25+20
— (none)0.00+0

The practical implication is that an S-grade weapon gives 3.5× the scaling bonus of an E-grade weapon at the same stat level. Weapons frequently change grade as you upgrade them: a weapon might start at D/D in Strength/Dexterity and reach B/B or even A/A at maximum upgrade, making the upgrade path itself a core part of build optimization in Elden Ring.

When using the Elden Ring damage calculator, always enter the grade after your intended upgrade level, not the +0 grade shown in the inventory. A fully upgraded weapon can dramatically outperform the same weapon at low upgrade even with identical base damage, purely due to the improved scaling grade.

Two-Handing, Counter Hits, and Charged Attacks

Three optional modifiers in the Elden Ring damage calculator reflect mechanics that meaningfully change your effective output in combat.

Two-Handing. Gripping your weapon with both hands multiplies your effective Strength by 1.5 (floored). This is one of the most efficient damage boosts available to Strength builds because it costs no rune investment. A character sitting at 40 Strength jumps to an effective 60 Strength — crossing a major soft-cap threshold — simply by two-handing. For builds that plan to two-hand, you can often save 20 Strength levels and invest those runes elsewhere.

Counter Hits. Elden Ring rewards attacking an enemy that is in the middle of their own attack animation. Hitting during this window is called a counter hit and multiplies your total AR by 1.15 (a 15% increase). The bonus applies to the full AR value including scaling, making it proportionally more valuable on high-AR builds. Weapons with long reach or hyper armor — such as colossal weapons — are especially good at intentionally fishing for counter hits.

Charged Heavy Attacks. Holding the heavy attack button instead of tapping it charges the attack, increasing your AR by a flat 30% multiplier. Charged attacks deal substantially more damage but leave you briefly vulnerable. They are most effective in situations where the enemy is staggered, knocked down, or otherwise unable to interrupt your windup.

If you tick both Counter Hit and Charged Attack in the calculator, the multipliers stack: total AR is first multiplied by 1.15 and then by 1.30, for a combined 1.495× damage multiplier over the base AR. Landing a charged counter hit is one of the highest single-hit damage outputs achievable without a critical attack in Elden Ring.

Enemy Defense and Damage Negation

After your AR is calculated, two enemy-side stats reduce the actual damage your HP bar sees removed from the enemy.

Flat Defense. Every enemy has a flat defense value per damage type (Physical, Strike, Slash, Pierce, Fire, Lightning, Holy, Magic). The defense reduction formula is: defenseReduction = 100 / (enemyDefense + 100). This means the reduction curve is hyperbolic — going from 0 to 100 defense cuts damage by 50%, but going from 100 to 200 defense only cuts damage by an additional 17%. High-defense enemies like late-game bosses and Golem variants are not immune to AR; they just require significantly higher AR to deal meaningful hits.

Damage Negation. Negation is a percentage applied on top of flat defense. A 20% negation means 80% of the post-defense value reaches the enemy's health. Negation percentages are usually lower than they appear in community wikis because multiple sources of negation sometimes interact differently. For this calculator, enter the single combined negation percentage for the encounter.

A key insight from the formula: increasing your AR has diminishing returns against high-defense enemies, but increasing your AR always increases final damage because the defense fraction is a fixed ratio. Doubling your AR doubles your final damage regardless of enemy defense level — so raw AR maximization is always worthwhile. The Elden Ring damage calculator lets you model this by trying different stat values against the same enemy defense to find efficient thresholds.

Optimizing Your Build with the Damage Calculator

The most effective use of the Elden Ring damage calculator is finding the point where investing more levels into an attribute stops paying off relative to alternative investments. Elden Ring's scaling has soft caps at approximately 20, 40, 60, and 80 for most attributes. The returns per level drop noticeably at each cap, though the linear model in this calculator provides a clear comparison baseline.

For pure Strength builds using the two-handing option, the effective Strength cap from actually leveling sits around 60 (which becomes an effective 90). Leveling Strength beyond 60 while two-handing still helps, but the return per level is lower. Many Strength builds instead invest those surplus runes into Vigor for survivability or Endurance for equip load.

Dexterity builds typically aim for 70–80 Dexterity to maximize scaling on A and S grade weapons. Because DEX scaling follows the same linear model in this calculator, you can directly compare the final damage gained from adding 5 DEX versus 5 Vigor — a common late-game optimization decision.

Mixed Strength/Dexterity builds (quality builds) spread investment across both stats. The calculator lets you instantly visualize the combined scaling bonus, making it straightforward to find the split that maximizes AR for a given total rune budget. Enter both scaling grades, adjust the sliders, and watch the attack rating update in real time.

When comparing weapons for a specific fight, always enter that boss's defense and negation values. A weapon that leads in AR on paper may underperform on a boss with high physical defense if the alternative weapon deals a damage type with lower negation — a nuance this calculator surfaces immediately.

Worked Examples

Default Warrior Setup

Problem:

A weapon with 100 base damage, C-grade STR scaling, D-grade DEX scaling, 40 STR, 20 DEX, no two-handing. Enemy has 100 defense and 20% negation.

Solution Steps:

  1. 1Effective Strength = 40 (no two-handing)
  2. 2STR scaling bonus = 100 × 0.75 × (40/100) = 100 × 0.75 × 0.40 = 30
  3. 3DEX scaling bonus = 100 × 0.50 × (20/100) = 100 × 0.50 × 0.20 = 10
  4. 4Total AR = 100 + 30 + 10 = 140 (no counter hit, no charged attack)
  5. 5Defense reduction = 100 / (100 + 100) = 0.50
  6. 6Negation reduction = 1 − (20/100) = 0.80
  7. 7Final damage = 140 × 0.50 × 0.80 = 56

Result:

Final Damage: 56. The weapon deals 56 HP per clean hit against this enemy.

Two-Handed Strength Build vs. Armored Boss

Problem:

A colossal weapon with 150 base damage, B-grade STR scaling, no DEX scaling, 60 STR two-handed. Boss has 120 defense and 15% negation.

Solution Steps:

  1. 1Effective Strength = Math.floor(60 × 1.5) = Math.floor(90) = 90
  2. 2STR scaling bonus = 150 × 1.00 × (90/100) = 150 × 0.90 = 135
  3. 3DEX scaling bonus = 150 × 0.00 × (10/100) = 0
  4. 4Total AR = 150 + 135 + 0 = 285
  5. 5Defense reduction = 100 / (120 + 100) = 100/220 ≈ 0.4545
  6. 6Negation reduction = 1 − (15/100) = 0.85
  7. 7Final damage = 285 × 0.4545 × 0.85 ≈ 285 × 0.3864 ≈ 110

Result:

Final Damage: 110. Two-handing added 30 effective Strength for free, lifting AR from a hypothetical 208 (one-handed) to 285.

Charged Counter Hit — Maximum Single-Hit Damage

Problem:

A katana with 120 base damage, A-grade STR scaling, C-grade DEX scaling, 50 STR, 30 DEX, one-handed. Counter hit AND charged attack both active. Enemy has 80 defense and 10% negation.

Solution Steps:

  1. 1Effective Strength = 50 (one-handed)
  2. 2STR scaling bonus = 120 × 1.25 × (50/100) = 120 × 1.25 × 0.50 = 75
  3. 3DEX scaling bonus = 120 × 0.75 × (30/100) = 120 × 0.75 × 0.30 = 27
  4. 4Base total AR = 120 + 75 + 27 = 222
  5. 5Counter hit × 1.15: 222 × 1.15 = 255.30
  6. 6Charged attack × 1.30: 255.30 × 1.30 = 331.89
  7. 7Defense reduction = 100 / (80 + 100) = 100/180 ≈ 0.5556
  8. 8Negation reduction = 1 − 0.10 = 0.90
  9. 9Final damage = 331.89 × 0.5556 × 0.90 ≈ 331.89 × 0.50 ≈ 166

Result:

Final Damage: 166. The combined 1.495× multiplier from counter + charged more than doubled the base hit damage of 56 (same weapon, no modifiers).

S-Grade Scaling at High Stat Investment

Problem:

A faith/strength hybrid weapon repurposed: 200 base damage, S-grade STR scaling, no DEX scaling, 80 STR, one-handed. Enemy has 150 defense and 25% negation.

Solution Steps:

  1. 1Effective Strength = 80 (one-handed)
  2. 2STR scaling bonus = 200 × 1.75 × (80/100) = 200 × 1.75 × 0.80 = 280
  3. 3DEX scaling bonus = 0
  4. 4Total AR = 200 + 280 = 480
  5. 5Defense reduction = 100 / (150 + 100) = 100/250 = 0.40
  6. 6Negation reduction = 1 − 0.25 = 0.75
  7. 7Final damage = 480 × 0.40 × 0.75 = 480 × 0.30 = 144

Result:

Final Damage: 144. Despite the high enemy defense and negation, the S-grade scaling at 80 STR generates 280 bonus damage on top of 200 base, resulting in solid output.

Tips & Best Practices

  • ✓Always enter the scaling grade for your weapon's CURRENT upgrade level, not the base +0 grade — scaling often improves significantly at higher upgrades.
  • ✓Use the two-handing checkbox even if you normally one-hand: if the damage jump is large, consider one-handing a shield only when you actually need it.
  • ✓Test your build against the specific boss you're struggling with by entering that boss's defense and negation values from a community wiki.
  • ✓A 30% charged attack bonus is usually worth the wind-up on enemies that are stunned or knocked down — use this calculator to confirm the damage increase before committing to the risky playstyle.
  • ✓Counter hits (+15%) reward aggressive play against enemies with slow attack animations. Fast weapons that can reliably hit during enemy swings effectively have a passive 15% damage bonus in those matchups.
  • ✓When comparing two weapons with similar AR, remember that attack speed matters too — a weapon that swings twice as fast but deals 60% of the damage per hit still wins on DPS.
  • ✓If your final damage seems low despite high AR, the culprit is usually high enemy damage negation — reducing the negation percentage by switching to a different damage type (slash vs. strike) can be more effective than adding 20 more stat levels.
  • ✓The effective Strength cap while two-handing is 99 (since the game caps stats at 99). This means one-handing at 66+ STR gives the same effective STR as two-handing at 66 STR — there is no benefit to two-handing above 66 STR for the Strength bonus itself.

Frequently Asked Questions

Two-handing increases your effective Strength by 50%, which increases your STR scaling bonus. If the weapon has no Strength scaling (grade — or E), two-handing provides no damage benefit — only stance benefits. The damage gain is largest on weapons with high Strength scaling grades (A or S) and is most impactful for characters with Strength in the 40–60 range, where the effective boost crosses a soft-cap threshold.
Defense is a flat stat that interacts with your AR through the formula: 100 / (defense + 100). Negation is a percentage deducted from what survives the flat defense check. They are applied sequentially, not combined. An enemy with 0 defense but 50% negation will halve your final damage, while an enemy with 200 defense and 0% negation reduces your damage by 67% through the flat formula. High-defense enemies require high AR to deal meaningful hits; high-negation enemies require any AR but lose half regardless.
Yes, they stack multiplicatively. A counter hit multiplies total AR by 1.15, and a charged attack multiplies it by 1.30. If both conditions are met simultaneously, the combined multiplier is 1.15 × 1.30 = 1.495 — roughly 50% extra damage over a standard light attack. This is achievable with colossal weapons or poke weapons that can safely charge against a staggered or downed enemy.
The defense formula — 100 / (enemyDefense + 100) — is hyperbolic, meaning each additional point of defense provides progressively less reduction. Going from 0 to 100 defense cuts damage by 50%, but going from 200 to 300 defense only cuts damage by about 11% more. This means very high AR attacks remain effective even against heavily armored bosses, and it explains why maximizing AR is more efficient than defense-bypassing strategies in most scenarios.
The primary soft cap for Strength scaling occurs around 40 Strength for most weapons. When two-handing, 40 STR becomes 60 effective STR, which sits at the second soft cap. Leveling Strength to 60 (effective 90 when two-handing) captures nearly all available scaling. Beyond 60 STR, the per-level gain diminishes noticeably, and redirecting further runes into Vigor or Endurance typically provides more overall benefit for survivability and stamina.
Quality build weapons scale from both attributes simultaneously. Enter the weapon's STR grade in the first dropdown and its DEX grade in the second. The calculator adds both scaling bonuses to the base damage to produce the combined AR. For example, a B/B quality weapon at 40 STR / 40 DEX produces (baseDamage × 1.0 × 0.40) + (baseDamage × 1.0 × 0.40) = 0.80 × baseDamage in total scaling bonus — the same as a single B-grade weapon at 80 in one stat.
Yes. Enter the base damage and scaling grades for your first weapon, note the final damage output, then change the inputs to your second weapon. Since the calculator is real-time, you can compare back and forth quickly. Make sure to use the same enemy defense and negation values for a fair comparison. Also ensure you enter post-upgrade scaling grades, as weapons often improve their grade significantly from +0 to maximum upgrade.
