Spell Haste appears as an equipment statistic in Dimraeth, but a reliable formula for its effect is not established by the available Early Access documentation. The Hasty item modifier grants the stat, and a community gear calculator lists it on several equipment slots. Neither source establishes whether a particular value changes casting time, cooldown duration, or both. Treat a claimed percentage conversion as unverified until it matches your current game tooltip and a repeatable comparison.
There is also a utility spell called Haste. Its recorded effect increases an ally's movement speed. That spell is a separate ability; its name does not explain what the equipment statistic does. Keeping those two entries separate prevents a misleading answer to a question about gear.
Find Spell Haste on gear
The Into Indie Games character guide identifies Hasty as an item modifier that gives Spell Haste, alongside examples such as Sharp for critical rate. This supports looking at the complete item description rather than assuming that every similarly named item rolls the same statistics. Equipment can combine a set identity with modifiers, and upgrades can alter the values or additional modifiers.
The community Gorehorn calculator lists Spell Haste in the Charm secondary pool, the Amulet primary and secondary pools, and the Bracer primary and secondary pools. Those options do not guarantee the stat on every drop.
For a player comparing two items, the actionable check is the actual line on each item's tooltip. Note the displayed value and all other differences before equipping the replacement. A change in item name is insufficient evidence of a change in Spell Haste, especially if the same replacement also changes a set bonus or a different combat statistic.
| Question | Supported answer |
|---|---|
| Does Spell Haste exist as a gear statistic? | Yes; it is named in the character guide and equipment calculator. |
| Does Hasty identify a Spell Haste modifier? | The character guide describes that association. Check the resulting item tooltip. |
| Can certain gear slots roll it? | The community Gorehorn calculator lists Charm, Amulet and Bracer pools containing it. |
| Does every spell become faster? | No universal effect has been established. |
| Is a particular value equal to a particular cooldown reduction? | The available documentation does not give a verified conversion. |
Haste the spell is a different entry
The fan spell database describes Haste as a utility spell cast on a friend, granting increased movement speed for seven seconds. Its listed entry lists twelve concentration and a twenty-two-second cooldown. These are dated community values and should be compared with the live tooltip before planning a rotation around them.

Community spell reference for the movement ability, separate from the Spell Haste equipment statistic.
The important distinction is the affected system: movement speed belongs to the described spell effect. Spell Haste belongs to an equipment line. The spell's duration, cost and cooldown do not supply an equipment formula. Equipping a Hasty item is not evidence that you have learned the Haste spell, and finding the spell entry is not evidence of a particular cast-speed increase.
Cooldown passives do not define Spell Haste
The October 5 developer patch notes give one precise cooldown change: Permafrost Rhythm cuts running cooldowns by one percent per stack, matching its node description. That is evidence about a named passive. It does not prove that the equipment statistic uses the same percentage, affects the same timers or stacks in the same order.
Keep the source of a change attached to the change itself. If a cooldown becomes shorter while Permafrost Rhythm is active, you have observed the combination of the skill and your equipment. You have not isolated the contribution of Spell Haste. A build can include several effects with similar visible outcomes, even when their rules differ.
Compare one change at a time
If the current interface still leaves the effect unclear, a controlled comparison is more useful than copying a formula from another game. The following comparison can test a particular setup, without establishing a universal formula.
Start with a baseline you can describe. Record your game version, selected spell, relevant passives, gear and displayed Spell Haste. Note whether you are alone or in a hosted session. Preserve the original items so that you can switch back without depending on another random drop.
Choose two setups that differ as little as possible. Ideally, change one item with a known Spell Haste difference while retaining the same spell and passive configuration. If the new item also changes a set bonus, concentration, damage or another relevant statistic, write those differences down. An imperfect comparison can still be useful, but it cannot support a clean numerical formula.
Observe casting and cooldown separately. For casting, compare the same input and animation under the same conditions. For cooldown, compare the time at which the ability becomes usable again. A faster animation is not automatically a shorter cooldown, and a shorter cooldown is not automatically a faster animation. Keep any visible movement-speed buff separate from both observations.
Repeat the comparison in both directions: baseline, replacement, then baseline again. One successful cast can be distorted by a different input timing, interruption, enemy interaction or recording frame. Repetition helps you find a consistent observation without claiming more precision than your recording supports.
Decide whether the item helps your actual build
A Spell Haste roll is one feature of a complete item. The character guide describes equipment sets that can change skill behavior as well as ordinary statistics. That means an item with more haste can still be a poor replacement if it removes an interaction your build depends on.
Compare the entire tooltip and keep the question concrete: does this replacement improve the spell sequence you actually use? Concentration management, available abilities and compatible set effects remain relevant even when a speed-related stat looks attractive. A benefit that cannot be demonstrated in your usual sequence should not be treated as a proven damage increase.
Questions that remain unanswered
A universal formula, cap, stacking order, and effects on channels or damage-over-time ticks remain unverified. If no difference is visible in your comparison, report that result for the tested spell and gear rather than concluding the stat is universally broken.
For now, read Spell Haste as a real gear statistic with an incompletely documented effect. Keep Haste's movement buff and Permafrost Rhythm's stated cooldown behavior in their own categories, and let the current tooltip and a controlled comparison guide an individual equipment choice.
