Haste is a status effect that comes in three different kinds: Weak[3], normal, and improved. Weak Haste is not available to players in Baldur's Gate II: Enhanced Edition.

  • The durations of effects present on a hastened creature remain unchanged. This is true even for ticking effects: They tick a lot more often but will wear out at the same point in time whether hastened or not.
  • Fatigue is not increased by any type of Haste effect. The Haste spell just happens to bundle a Fatigue effect and a normal Haste effect.
  • When dual-wielding and hastened, the total attacks per round is split in such a way that the off-hand gets 2 APR, no more, no less, and the main hand receives whatever remains.[5] In some cases, this can cause the main hand to lose 0.5 APR. For example if a non-hastened fighter has 3.5 APR when wielding two weapons, it is split 2.5 for the main hand and 1 for the off-hand. Normal Haste will boost APR to 4, but the main hand will now only have 2 APR because the off-hand must have 2.

    The Paws of the Cheetah do not actually grant any type of Haste in Enhanced Editions. They only set base movement speed to 200% and add a "fake" Haste portrait icon. This is the reason why the speed increase from these boots can be stacked with Haste to reach 400% movement speed.

Stacking rules[]

  • Haste and Slow effects cancel each other out. They don't remove each other out but all of their effects are neutered until one of them wears out.
  • The slow type of Disease interacts with Haste in the same way.
  • Only one Haste can be active at any time on a given creature. If several Haste effects are applied, all but one are neutered.

Effect on tick rate[]

The following only applies to Enhanced Editions. In the original edition of Baldur's Gate II: Shadows of Amn, the multiplier discussed below is always x2, and the extra tick occurs halfway within the period.

Any effect that triggers repeatedly based on time is affected by the Haste effect. The main ones are Poison, Regeneration and the damage-inflicting types of Disease. All of them follow the same rules: The amount of triggers (or ticks) per unit of time is multiplied by the following factor.

Ticks once per X seconds Haste's ticks multiplier
≤ 1 x2
2 or 3 x3
4 to 7 x4
8 to 15 x5
16 to 31 x6
32 to 63 x7
... ...

Note: Regeneration granted by having a Constitution of 20 or higher is not sped up by Haste at all.

Besides the Poison, damage-inflicting Disease and Regeneration effects, the following items or spells obey the rule: [7]

Item or spell Ticks once per X seconds Haste's ticks multiplier
Creeping Doom 1 x2
Insect Plague 2 x3
Summon Insects 2 x3
Boots of Phasing 3 x3
The Brick 6 x4

Finally, effects from Blade Barrier, Globe of Blades, Repulse Undead, the Cloak of the Dark Moon and the Night Club are special in that they trigger approximately once per 100 AI ticks (once per 6⅔ seconds), and Haste grants them a x2 factor.[8]

It is worth noting that extra ticks are not spread out evenly within the effect's un-hasted tick period. Instead, the next tick occurs at 50% of the remaining time in the period, except for the last tick which occurs at the end. For example, an effect that ticks once per 60 seconds will tick 7 times per 60 seconds under Haste. But the first tick will not occur until the 30s mark, the second tick until the 45s mark, the third tick until 52.5s, etc, meaning that 4 out of the seven ticks will occur within the last 4 seconds. The 7th tick will occur at 60s.

What Haste does NOT do[]

The Haste effect halves round duration, but this doesn't have the wide implications of the Slow effect. In particular, the Haste effect does NOT:

  • Double spell casting speed
  • Let spells be cast twice as often
  • Let items be used twice as often
  • Make the creature twice as fast for all tasks in general



  • Create a separate article for Haste 2 (317) effect, used by Whirlwind Attack and Greater Whirlwind Attack, on the model of Hold creature 2
  • See interaction between the various Haste types and Haste 2
  • See if really all types of item abilities get speed factor and casting times halved. What about innate abilities? Quick items other than scrolls?
  • The original BG1 only supports normal haste, and there seems to be differences in what it does. Do tests to outline how it works and incorporate any difference in this article without it becoming cramped or confusing. Some research has happened on the Talk page already.
  • Still BG1: The infobox with Haste sources, immunities and cures might be quite different from other games  [verification needed]


  1. Baldur's Gate 2 with Throne of Bhaal installed and the latest patch, version 2.5.26498
  2. 2.0 2.1 2.2 This item uses the real Improved Haste spell
  3. Misnamed Movement rate only in Near Infinity
  4. The time it takes for a creature to fetch a spell scroll or ready an item ability before actually using it
  5. This is true in all cases but one: If APR is 2 while dual-wielding, Weak Haste will keep it at 2 as expected. But both attacks will come from the main hand, and none from the off-hand.
  6. Weak Haste seems to have the same priority as Improved, i.e. between these two, the last applied wins. The algorithm is unclear when Slow effects are added in between various Haste types.  [verification needed]
  7. They use effect Use EFF file on condition (272)
  8. They use Cast spell on condition (232) with condition ID 1-6, 8-9, 13-15 or 18-21. Other conditions do not trigger based on time but on events, and are therefore unaffected by Haste, like Target hit (ID 0, used by e.g. Fireshields).
