Formula Explanation:
Damage per Hit is calculated as (Attacker's effective attack - Defender's effective defense), with a minimum of 0. Effective attack considers your primary attack stat (Str/Mag), weapon might, and weapon triangle. Effective defense considers the enemy's relevant defense stat (Def/Res) and any flat engage bonuses.
Hit Rate is derived from your unit's Dexterity, Luck, weapon hit, and support bonuses versus the enemy's Speed, Luck, and terrain avoid bonuses.
Critical Rate factors in your unit's Dexterity and weapon critical chance, reduced by the enemy's Luck.
Follow-up Attack occurs if your unit's Attack Speed (Spd - Max(0, Weapon Weight - Build)) is 5 or more points higher than the enemy's Attack Speed.
Expected Damage is the weighted average of normal and critical damage, considering hit and crit rates, and total attacks.

What is the FE Engage Calculator?
The FE Engage Calculator is an essential tool for players of Fire Emblem Engage who wish to delve deeper into the game's combat mechanics and optimize their strategies. This calculator allows you to accurately predict the outcomes of battles by inputting various stats for both your unit and the enemy, along with weapon details and environmental modifiers. By providing a precise forecast of damage, hit rates, critical chances, and the potential for follow-up attacks, it empowers players to make informed decisions on the battlefield.
Who should use it? Any Fire Emblem Engage player looking to gain an edge will find this calculator invaluable. This includes:
- Strategists: For planning optimal unit positioning and attack orders.
- Unit Builders: To test the effectiveness of different stat allocations, weapon choices, and skill combinations.
- Theorycrafters: For understanding the underlying combat formulas and exploring hidden mechanics.
- Casual Players: To simply confirm if an attack will be lethal or if their unit can survive an enemy encounter.
Common Misunderstandings: While the calculator provides highly accurate predictions based on known game formulas, it's crucial to remember that Fire Emblem Engage, like all RPGs, involves a degree of randomness. The calculator provides percentages for hit and critical rates, but the actual outcome in-game is determined by the game's internal random number generator (RNG). A 90% hit rate doesn't guarantee a hit, just a very high probability. This tool helps you understand those probabilities, not eliminate them.
FE Engage Combat Formula and Explanation
Understanding the core formulas behind Fire Emblem Engage combat is key to mastering the game. Our FE Engage Calculator uses these very formulas to give you accurate predictions.
Core Combat Formulas:
- Effective Attack (EA):
- If Physical Weapon:
EA = Attacker_Str + Weapon_Might + Weapon_Triangle_Bonus + Attacker_Engage_Damage_Bonus - If Magical Weapon:
EA = Attacker_Mag + Weapon_Might + Weapon_Triangle_Bonus + Attacker_Engage_Damage_Bonus
Weapon Triangle Bonus: +1 Might for Advantage, -1 Might for Disadvantage, 0 for Neutral.
- If Physical Weapon:
- Effective Defense (ED):
- If Physical Weapon:
ED = Defender_Def + Defender_Engage_Defense_Bonus - If Magical Weapon:
ED = Defender_Res + Defender_Engage_Defense_Bonus
- If Physical Weapon:
- Damage per Hit:
Max(0, EA - ED) - Critical Damage:
Damage_per_Hit * 3(standard for FE Engage) - Attacker Attack Speed (A_AS):
Attacker_Spd - Max(0, Weapon_Weight - Attacker_Bld) - Defender Attack Speed (D_AS):
Defender_Spd - Max(0, Defender_Weapon_Weight - Defender_Bld) - Follow-up Attack: Occurs if
A_AS >= D_AS + 5 - Base Hit:
(Attacker_Dex * 2) + (Attacker_Lck / 2) + Weapon_Hit + Attacker_Support_Hit_Bonus - Defender Avoid:
(Defender_Spd * 2) + (Defender_Lck / 2) + Defender_Terrain_Avoid_Bonus - Hit Rate:
Min(100, Max(0, Base_Hit - Defender_Avoid)) - Base Critical:
(Attacker_Dex / 2) + Weapon_Crit - Defender Critical Evade:
Defender_Lck - Critical Rate:
Min(100, Max(0, Base_Critical - Defender_Critical_Evade)) - Expected Damage (per round):
(Damage_per_Hit * (1 - Crit_Rate/100)) + (Critical_Damage * (Crit_Rate/100)) * Total_Attacks
Variable Explanations:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Strength (Str) | Physical attack power of a unit. | Points | 5 - 50 |
| Magic (Mag) | Magical attack power of a unit. | Points | 5 - 50 |
| Dexterity (Dex) | Influences Hit and Critical rates. | Points | 5 - 45 |
| Speed (Spd) | Influences Avoid and chance for Follow-up attacks. | Points | 5 - 50 |
| Luck (Lck) | Minor influence on Hit, Avoid, Crit, and Crit Evade. | Points | 0 - 40 |
| Build (Bld) | Reduces Speed penalty from heavy weapons. | Points | 0 - 20 |
| Defense (Def) | Reduces incoming physical damage. | Points | 5 - 45 |
| Resistance (Res) | Reduces incoming magical damage. | Points | 5 - 45 |
| Weapon Might | Base attack power added by the weapon. | Points | 0 - 25 |
| Weapon Hit | Base accuracy added by the weapon. | % | 60 - 100 |
| Weapon Crit | Base critical chance added by the weapon. | % | 0 - 30 |
| Weapon Weight | Penalty to Attack Speed if higher than Build. | Points | 1 - 20 |
Practical Examples with the FE Engage Calculator
Let's walk through a couple of scenarios to see how the FE Engage Calculator can help you strategize.
Example 1: A Fast Swordmaster vs. a Sturdy General
Imagine your Swordmaster, highly agile but not exceptionally strong, is facing a heavily armored General.
- Your Unit (Swordmaster):
- Str: 30, Mag: 10, Dex: 35, Spd: 40, Lck: 25, Bld: 10
- Weapon: Silver Sword (Might: 12, Hit: 90%, Crit: 10%, Weight: 8, Type: Physical)
- Modifiers: Neutral Weapon Triangle, 5% Support Hit Bonus, 0% Terrain Avoid, 0 Flat Engage Damage
- Enemy Unit (General):
- HP: 60, Def: 38, Res: 15, Spd: 15, Lck: 10, Bld: 15
- Weapon Weight: 12
- Modifiers: 0% Terrain Avoid, 0 Flat Engage Defense
Predicted Results:
- Damage per Hit: 4
- Hit Rate: 95%
- Critical Rate: 15%
- Follow-up Attack: Yes
- Total Attacks: 2
- Expected Damage: ~10-12 (Enough to chip, but not one-shot)
Analysis: Your Swordmaster's high Speed allows for a follow-up, and high Dex/Lck ensures good accuracy and a decent crit chance. However, the General's immense Defense severely limits damage output per hit. This tells you that while your unit can hit reliably, they won't be dealing significant damage alone. You might need magical allies or armor-piercing weapons.
Example 2: A Mage Attacking a High-Resistance Griffin Knight
Now, let's consider a powerful Mage against a speedy, magic-resistant flying unit.
- Your Unit (Sage):
- Str: 5, Mag: 40, Dex: 25, Spd: 28, Lck: 20, Bld: 5
- Weapon: Thoron (Might: 12, Hit: 85%, Crit: 0%, Weight: 9, Type: Magical)
- Modifiers: Neutral Weapon Triangle, 0% Support Hit Bonus, 0% Terrain Avoid, 5 Flat Engage Damage (e.g., from Celica)
- Enemy Unit (Griffin Knight):
- HP: 50, Def: 20, Res: 30, Spd: 35, Lck: 20, Bld: 8
- Weapon Weight: 6
- Modifiers: 10% Terrain Avoid (forest), 0 Flat Engage Defense
Predicted Results:
- Damage per Hit: 17
- Hit Rate: 70%
- Critical Rate: 2.5%
- Follow-up Attack: No
- Total Attacks: 1
- Expected Damage: ~12-13
Analysis: Despite high Magic and a potent tome, the Griffin Knight's high Resistance and Speed (leading to no follow-up and good avoid) make this a less reliable engagement. The 70% hit rate means there's a significant chance to miss, which can be critical. This might prompt you to use a unit with higher Hit, or apply a "Surefire" type skill to guarantee a hit, or consider a physical attacker instead.
How to Use This FE Engage Calculator
Using the FE Engage Calculator is straightforward, designed for quick and accurate combat predictions.
- Input Your Unit's Stats: Start by entering your attacker's Strength, Magic, Dexterity, Speed, Luck, and Build. These values are typically found on your unit's status screen in-game.
- Enter Attacker Weapon Details: Provide the Might, Hit, Crit, and Weight of the weapon your unit is using. Select whether it's a Physical or Magical weapon and its Weapon Triangle advantage/disadvantage against the enemy.
- Add Attacker Modifiers: Account for any additional bonuses your unit receives, such as Support Hit Bonus from adjacent allies, Terrain Avoid Bonus from standing on advantageous tiles, or flat Damage Bonuses from active Engage skills (e.g., Marth's Lodestar Rush, Celica's Echo).
- Input Enemy Unit's Stats: Enter the enemy's current HP, Defense, Resistance, Speed, Luck, and Build. You can usually find these by selecting the enemy unit in-game.
- Enter Enemy Weapon Weight & Modifiers: Input the enemy's weapon weight (important for follow-up calculations). Also, account for any Terrain Avoid Bonus the enemy receives or flat Defense/Resistance Bonuses from their own Engage skills.
- Review Results: The calculator will instantly update the "Combat Results" section. Here you'll see the Damage per Hit, Hit Rate, Critical Rate, and whether a Follow-up Attack will occur. The "Expected Damage" provides an average damage output per combat round, taking probabilities into account.
- Interpret and Adjust: Use these results to inform your tactical decisions. If the damage is too low, or the hit rate too risky, consider switching targets, using a different unit, applying buffs, or changing weapons.
Remember to always double-check your inputs against the game to ensure the most accurate predictions.
Key Factors That Affect Combat in FE Engage
Mastering combat in Fire Emblem Engage goes beyond just high stats. Many interconnected factors influence the outcome of every battle:
- Core Stats (Str/Mag, Def/Res): These are the most direct contributors to damage dealt and taken. High Strength or Magic is crucial for offense, while high Defense or Resistance is vital for survivability against physical or magical threats, respectively.
- Speed (Spd): A high Speed stat is incredibly powerful, as it dictates Avoid (making your unit harder to hit) and the ability to perform or prevent Follow-up Attacks, effectively doubling your damage or preventing the enemy from doing so. This is often the most important stat for offensive units.
- Dexterity (Dex) and Luck (Lck): Dexterity heavily influences your unit's Hit Rate and Critical Rate, ensuring your attacks land and potentially deal massive damage. Luck plays a smaller, but still significant, role in refining Hit, Avoid, Crit, and Crit Evade.
- Weapon Choice: The weapon you equip is paramount. Its base Might directly adds to your attack, while its Hit and Crit values determine accuracy and critical potential. Weapon Weight, when greater than your unit's Build, can significantly reduce your Attack Speed, potentially costing you a follow-up. Choosing the right weapon type (e.g., physical vs. magical) is also key against different enemy defenses.
- Weapon Triangle: A classic Fire Emblem mechanic, the Weapon Triangle grants a small Might bonus for advantage (+1) and penalty for disadvantage (-1). While seemingly minor, these small adjustments can be decisive in tight situations, especially when combined with other modifiers.
- Engage Skills and Abilities: Emblem Rings bring a host of powerful skills that dramatically alter combat. These can include flat damage bonuses (e.g., Marth's Lodestar Rush), stat boosts, unique attack types, or defensive buffs. Integrating these into your combat plan is essential for maximizing output.
- Terrain Effects: The battlefield itself is a crucial factor. Standing on certain tiles (e.g., Forests, Forts) can grant significant Avoid and/or Defense/Resistance bonuses, making units harder to hit or damage. Always consider terrain for both your units and the enemies.
- Support Bonuses: Adjacent allies often provide minor but helpful bonuses to Hit, Avoid, and sometimes Crit. Positioning your units to maximize these support bonuses can turn the tide of battle.
Frequently Asked Questions (FAQ) about the FE Engage Calculator
Q1: How accurate is this FE Engage Calculator?
A: This calculator is designed to be highly accurate, utilizing the widely accepted combat formulas from Fire Emblem Engage. While it cannot account for every single obscure skill or hidden modifier in the game, it provides a very reliable prediction for standard combat scenarios. Minor discrepancies might arise from in-game rounding or very specific, situational skills not included.
Q2: Does this calculator account for all skills and Emblem Ring abilities?
A: The calculator includes fields for common flat damage/defense bonuses and general support/terrain effects. It does not individually list every single skill or Emblem Ring ability due to the vast number and complexity. For specific skills (e.g., Wrath, Vantage, Lance Power), you would need to manually adjust relevant stats (like Crit or Might) based on the skill's effect before inputting them into the calculator.
Q3: Why do my in-game results sometimes differ from the calculator's predictions?
A: The most common reason for discrepancies is the game's internal Random Number Generator (RNG) for hit and crit rates. The calculator provides probabilities (e.g., 80% Hit), but the actual outcome is still a roll of the dice. Other reasons could be overlooking a small buff/debuff in-game, terrain effects, or specific enemy passive skills not factored into your inputs.
Q4: What is "Build" and why is it important?
A: Build (Bld) is a stat that helps your unit wield heavy weapons without suffering a significant Speed penalty. If a weapon's Weight is higher than your unit's Build, the difference is subtracted from your unit's Speed when calculating Attack Speed (AS). This can be crucial for securing or preventing follow-up attacks.
Q5: How does Luck affect combat in FE Engage?
A: Luck has a minor but broad impact. It contributes to both Hit and Avoid rates (halved compared to Dexterity/Speed contributions) and directly affects your Critical Rate and the enemy's Critical Evade. Higher Luck generally means better overall combat reliability.
Q6: What is a follow-up attack?
A: A follow-up attack occurs when your unit's Attack Speed (AS) is 5 or more points higher than the enemy's AS. This allows your unit to attack twice in a single combat round, dramatically increasing your damage output. Conversely, if the enemy has a significantly higher AS, they might land a follow-up on your unit.
Q7: My hit rate is very low/high, what can I do?
A: If your hit rate is low, consider units with higher Dexterity or Luck, using weapons with higher base Hit, leveraging support bonuses from adjacent allies, or moving to terrain that offers an Avoid bonus (for the enemy) or no Avoid bonus (for your unit). If it's very high, you're likely facing a slow, low-Dex/Lck enemy, or your unit is exceptionally accurate.
Q8: Can I save my calculations or share them?
A: This single-page calculator does not have a built-in save or share function. However, you can use the "Copy Results" button to easily transfer the output to a text document or share it with others. For long-term tracking, we recommend taking screenshots of your inputs and results.
