Haste
| Name | Haste |
|---|---|
| Abbr | haste |
| Brief | A chance to gain an extra attack or spell action immediately after attacking |
| Formula | (hastePercent, roll) => roll <= hastePercent |
Haste is an attack attribute that grants a chance to take an additional attack or spellcasting action immediately after making an attack. Unlike other attributes, Haste is probabilistic—it doesn't always trigger, but when it does, it's extremely powerful.
How It Works
When you make an attack or cast a spell, you have a chance equal to your Haste percentage to immediately gain another attack or spellcasting action:
On attack/spell: Roll d100
If roll ≤ Haste%, gain extra action
Carryover Mechanic
If the Haste proc fails, the "leftover" probability carries over to your next turn:
Next turn Haste chance = base Haste% + carryover from previous failed rolls
This means if you have 20% Haste and fail the roll, next turn you effectively have 40% chance (assuming your base is still 20%). This carryover continues until you proc, at which point it resets.
Example
Character with 25% Haste:
| Turn | Effective Chance | Roll | Result | Carryover |
|---|---|---|---|---|
| 1 | 25% | 42 | Miss | 25% |
| 2 | 50% | 31 | Miss | 50% |
| 3 | 75% | 60 | Miss | 75% |
| 4 | 100% | -- | Hit! | 0% |
With carryover, you're guaranteed to eventually proc. Higher base Haste means more frequent procs.
Sources of Haste
Magic Weapons
Some enhanced weapons grant a Haste percentage:
| Enhancement | Haste |
|---|---|
| Swift weapon | 10-15% |
| Speed weapon | 20-25% |
| Legendary speed weapon | 30%+ |
Spells
The Haste spell grants significant action economy benefits, which may include Haste percentage.
Class Features
Some martial classes gain speed-related abilities that function similarly to Haste.
Strategic Considerations
Haste is most valuable when:
- You deal high damage per attack (more attacks = more total damage)
- You have abilities that trigger per attack
- Combat is long enough for the carryover to matter
- Combined with action economy abilities
Haste vs. Other Attack Attributes
| Attribute | Effect | Reliability |
|---|---|---|
| Hit Rating | Better accuracy | Always applies |
| Hit Power | More damage per hit | Always applies |
| Crit Rating | More critical hits | Per-attack chance |
| Crit Power | Bigger crits | When you crit |
| Haste | Extra attacks | Probabilistic, carryover |
Haste has the highest variance but potentially the highest ceiling—an extra attack is essentially doubling your output for that turn.
Diminishing Returns
Unlike flat bonuses, Haste has some effective diminishing returns at very high levels. At 50% Haste, you average 2 attacks per turn. At 100% Haste, you'd get 2 guaranteed, but there's no benefit beyond that. Practical Haste values are usually 10-40%.
