Armor
Every unit in the game has an armor type and attack type. Each attack type is better or worse against other armor types. For example, a Grunt has a Normal attack, which does 150% damage versus “Medium” armor units like the Archer, Rifleman, Troll Headhunter and Crypt Fiend. The Archer has a Pierce attack, which does 100% extra damage versus “Light” armor units like the Gryphon Rider. Ethereal units can only be damaged by units that have the attack type “Magic” such as spellcasters. Magic-immune units can only be damaged by units that have physical attack types. Using the right counter units is very important. Here is a table of all armor and attack types and the bonus damage they deal.
| Light | Medium | Heavy | Fortified | Hero | Unarmored | |
|---|---|---|---|---|---|---|
| Normal | 100% | 150% | 100% | 70% | 100% | 100% |
| Pierce | 200% | 75% | 100% | 35% | 50% | 150% |
| Siege | 100% | 50% | 100% | 150% | 50% | 150% |
| Magic | 125% | 75% | 200% | 35% | 50% | 100% |
| Chaos | 100% | 100% | 100% | 100% | 100% | 100% |
| Spells | 100% | 100% | 100% | 100% | 70% | 100% |
| Hero | 100% | 100% | 100% | 50% | 100% | 100% |
But how does this work when the amount of armor is increased?
For positive armor, damage is reduced by = ((armor) * 0.06) / (1 + 0.06 * (armor))
For negative armor, damage is increased by = 2 – 0.94 ^(-armor)
This gives the following numbers:
| Armor | Damage increase / decrease |
|---|---|
| -10 | 46,14% |
| -5 | 26,61% |
| -4 | 21,93% |
| -3 | 16,94% |
| -2 | 11,64% |
| -1 | 6,00% |
| 0 | 0,00% |
| 1 | 5,66% |
| 2 | 10,71% |
| 3 | 15,25% |
| 4 | 19,35% |
| 5 | 23,08% |
| 6 | 26,47% |
| 7 | 29,58% |
| 8 | 32,43% |
| 9 | 35,06% |
| 10 | 37,50% |
| 15 | 47,37% |
| 20 | 54,55% |
| 50 | 75,00% |
Example: A unit with 50 “Pierce” attack is attacking a unit with 10 “Medium” armor. 10 armor is a reduction of 37.50%. Also, pierce damage does only 75% damage against medium armor. So eventually, the unit will deal only: 50 * (1 – 0,375) * 0,75 = 23,44 damage.
