Battle Round Calculator
Estimate one combat exchange in The Battle of Polytopia using attack, defense, health, and terrain bonus values.
Why use a Polytopia battle calculator?
Polytopia rewards positioning, tempo, and efficient trades. A battle calculator helps you preview whether an attack secures a knockout, leaves your unit exposed, or softens a target for a follow-up hit. Instead of guessing, you can make faster and safer decisions during tight turns.
How to read the results
Damage to Defender
This is the estimated HP removed from the defending unit after one attack. If the number is greater than the defender's current HP, the defender is defeated.
Retaliation Damage
If the defender survives and can retaliate, your attacker may take damage in return. Turning off retaliation is useful for situations like attacks from units that avoid a counterattack due to range or special interaction.
Remaining HP
The calculator reports post-combat HP for both sides. In practice, this is often the most important output because it tells you whether either unit becomes easy to finish by nearby enemies.
What affects battle outcomes?
- Attack stat: Higher attack pushes damage up quickly.
- Defense stat: Higher defense reduces incoming damage and improves retaliation potential.
- Current HP ratio: Damaged units fight worse than healthy ones.
- Defense bonus: Terrain and defensive setups can dramatically increase survivability.
Practical strategy tips
1) Trade up, not sideways
If your attacker takes heavy retaliation and fails to secure a kill, the exchange may be negative. Check the remaining HP values before committing.
2) Finish low-HP targets first
Since combat power scales with current health, removing weakened enemies denies them meaningful retaliation on future turns.
3) Respect defender bonus tiles
Even modest defense bonuses can turn a clean knockout into a failed attack. Always test with and without bonus values if terrain is uncertain.
4) Chain your turn plan
Use this tool for each expected exchange in sequence: opener, follow-up, and cleanup. That helps you avoid ending your turn with fragile front-line units.
Example planning workflow
- Enter your attacking unit's current HP and attack value.
- Enter the target's defense and current HP.
- Add terrain/city defense bonus if applicable.
- Run the calculation and note remaining HP.
- Adjust for a second potential attacker and repeat.
Limitations and best use
This calculator is designed for quick tactical planning of a single exchange, not full-turn simulation with every game modifier. Treat the result as a high-quality estimate and combine it with your board awareness, movement ranges, and reinforcement timing.
