Attack Speed
Attack Speed decreases the startup time of an autoattack and the cooldown time between each attacks. In simpler terms, it determines how fast a unit can attack. Attack speed is based on a unit's Base Attack Time, and is increases with Agility, attack speed stats, and abilities.
Base Attack Time
Base Attack Time determines how fast a unit attacks without any attack speed modifiers. BAT is measured in seconds between each attack. The lower the BAT, the faster the attack. All heroes have a BAT of 1.7 except the following:
| Hero | baseAttackTime |
|---|---|
| War Beast (w/ Metamorphosis) | 1.4 |
| Magebane | 1.6 |
| Pebbles (w/ Level 1 Enlarge) | 1.9 |
| Pebbles (w/ Level 2 Enlarge) | 2.1 |
| Pebbles (w/ Level 3 Enlarge) | 2.3 |
Formula
The formulas used to calculate attack time and attacks per second.
| Name | Formula |
|---|---|
| Attack Time | BAT / ((1 + (AS / 100)) × %AS × %AS Slow) |
| Attacks per Second | ((1 + (AS / 100)) × %AS × %AS Slow) / BAT |
Attack Speed Required to Increase Attacks per Second
Since HoN's servers run at 20 frames per second, a unit must reach the next 'step' in the server frame when attacking faster than once per second in order to receive an actual increase in damage output. This chart lists the amount of +Attack Speed required to increase actual attacks per second. This chart only applies to heroes with 1.7 BAT.
