Olden Era — Damage Calculator

Know the outcome before you commit the stack. Enter an attacker and defender to get min/average/max damage, kill counts, luck & morale odds and the expected retaliation — using the game's real damage formula. The URL updates as you type, so you can share any matchup.

🧪 Early Access balance is still moving, so unit presets are on hold until numbers stabilize — enter stats straight from the unit card for now. Presets land here as soon as they're verified (patrons get the update first).

How damage works in Olden Era

Every attack rolls a base damage between the unit's min and max, multiplies by stack size, then scales by (20 + ATK) / (20 + DEF) — equal stats cancel out, and defense can never make a stack invulnerable. Each point of positive luck adds a 6% chance of a 150% Lucky Strike (negative luck: 6% per point of a 50% strike). Each point of positive morale gives a 4% chance of an extra turn. Ranged units deal −50% in melee and lose 10% per hex past 4, capped at −50%. The "avg damage" figure folds the luck odds into the expected value; kills use the defender's per-unit HP; retaliation is computed from the survivors of the average roll.
