What is the Polytopia Damage Calculator?

A Polytopia Damage Calculator is an essential tool for any serious player of The Battle of Polytopia. It allows you to precisely calculate the outcome of a battle before you commit your units. By inputting variables such as unit stats, health, and terrain bonuses, you can see the exact amount of damage an attack will inflict, as well as the retaliation damage your unit will receive. This removes the guesswork from combat, enabling more strategic planning and optimal use of your forces, which is a key part of any advanced Polytopia strategies.

Polytopia Damage Formula and Explanation

The combat in Polytopia seems simple on the surface, but it’s governed by a specific mathematical formula. This polytopia damage calculator uses that exact formula to provide accurate results. The core calculation involves determining an “Attack Force” and a “Defense Force” and then using those values to find the final damage.

AttackForce = AttackerAttack * (AttackerHealth / AttackerMaxHealth)
DefenseForce = DefenderDefense * (DefenderHealth / DefenderMaxHealth) * DefenseBonus
                
TotalDamage = round( (AttackForce / (AttackForce + DefenseForce)) * AttackerAttack * 4.5 )

The health of a unit plays a crucial role; a damaged unit deals significantly less damage. This is represented by the `(Health / MaxHealth)` multiplier for both the attacker and defender.

Variables Table

Variable	Meaning	Unit	Typical Range
Attacker/Defender Attack	The base offensive power of a unit.	Stat Points	0.5 – 5
Attacker/Defender Defense	The base defensive power of a unit.	Stat Points	0 – 4
Health (HP)	The current hit points of a unit.	HP	1 – 40
DefenseBonus	A multiplier from terrain or walls.	Multiplier	1.0x, 1.5x, 4.0x
Veteran Bonus	A status that increases a unit’s combat effectiveness.	Status	Active / Inactive

Practical Examples

Example 1: Warrior vs. Warrior (Open Field)

A classic engagement. A full-health Warrior attacks another full-health Warrior in an open field.

• Attacker Inputs: Attack=2, Health=10, Max Health=10
• Defender Inputs: Defense=2, Health=10, Max Health=10, Terrain Bonus=1.0x
• Result: The attacking Warrior deals 5 damage. The defending Warrior retaliates with 4 damage. Both survive with 5 and 6 HP respectively. This is a fundamental interaction to learn for any polytopia combat guide.

Example 2: Catapult vs. Walled Giant

A powerful ranged unit trying to break through a city’s ultimate defense.

• Attacker Inputs: Attack=4, Health=10, Max Health=10
• Defender Inputs: Defense=4, Health=40, Max Health=40, Terrain Bonus=4.0x (Walled City)
• Result: The Catapult deals a mere 1 damage to the Giant. Since Catapults are ranged, there is no retaliation damage. Breaking a walled Giant is a significant undertaking.

How to Use This Polytopia Damage Calculator

1. Enter Attacker Stats: Input the base attack stat, current HP, and max HP for the attacking unit. Check the “Veteran” box if it has been promoted.
2. Enter Defender Stats: Input the base defense stat, current HP, and max HP for the defending unit. Check its veteran status.
3. Select Defense Bonus: Choose the appropriate defensive terrain from the dropdown. Remember, the defender must have the ‘Fortify’ skill to receive bonuses from cities or walls.
4. Review the Results: The calculator instantly shows the total damage the attacker will deal and the defender’s remaining health.
5. Check Intermediate Values: Look at the “Attacker Force,” “Defender Force,” and “Retaliation Damage” to better understand the mechanics of the battle and how different stats contribute. This is crucial for understanding the polytopia unit tier list in practice.

Key Factors That Affect Damage in Polytopia

• Health Percentage: The most critical factor. A unit at 50% health deals roughly half its potential damage. This is why focusing fire to eliminate units is more effective than spreading damage around.
• Defense Bonus: A unit in a forest (1.5x) or behind a wall (4.0x) becomes incredibly tough to defeat, drastically reducing incoming damage.
• Veteran Status: Veteran units gain +5 max HP and a 20% combat bonus (approximated here by a stat boost), making them significantly more powerful and durable.
• Poison: Poisoned units have their attack and defense stats reduced, making them much weaker in combat. This is a key ability for the Cymanti tribe.
• Unit Stats: The base Attack and Defense stats of units determine their core effectiveness. A high-attack unit will always have an advantage against a low-defense one. Knowing the polytopia unit stats is fundamental.
• Retaliation Damage: The defender also deals damage back to the attacker (unless the attacker is ranged). This is calculated similarly to the initial attack but uses the defender’s attack stat and the attacker’s defense stat.

Frequently Asked Questions (FAQ)

How is damage rounded in Polytopia?

The final damage value is rounded to the nearest whole number. For example, 4.5 damage becomes 5, and 4.4 becomes 4.

Do veteran bonuses stack with defense bonuses?

Yes. A veteran Defender in a walled city is one of the toughest things to destroy in the game, benefiting from its high base defense, veteran bonus, and the 4x wall multiplier.

Why does my Swordsman not get a defense bonus in a city?

Only units with the “Fortify” skill get a defense bonus on certain terrain like cities. Swordsmen do not have this skill, whereas units like Warriors and Defenders do.

How does poison work?

Poisoned units have their attack and defense stats permanently reduced by 30% for the rest of the game, even if healed back to full health. This calculator applies a simple stat reduction when the ‘Poisoned’ box is checked.

Why did my unit deal 0 or 1 damage?

This happens when the Defender’s `DefenseForce` is overwhelmingly higher than the Attacker’s `AttackForce`, often due to a massive defense bonus (like a wall) or a large health difference.

Can this calculator predict outcomes for splash damage units like Catapults?

This calculator is designed for direct 1-on-1 combat. It calculates the damage to the primary target but does not calculate the splash damage to adjacent units.

Is this polytopia damage calculator always 100% accurate?

Yes, it uses the widely accepted community-verified damage formula. Barring any game updates that change the formula, the results should match what you see in-game.

How do I know the outcome without a calculator?

In the game, you can select your attacking unit and then press-and-hold on a target. The game will show you the expected damage outcome. This calculator is for planning moves in advance or for theorycrafting.
