Slow Effect Fixes
SpeedMult Related Bugs
This mod makes a few changes to all the slowing (and technically also speed) effects in the game, to make them behave more consistently.
-
[]All effects that modify the "SpeedMult" Actor Value have been prevented from stacking. The strongest effect will apply, while weaker effects are ignored.
[
]A script has been attached to all these effects that causes the changes to movement speed to be applied correctly.Why this mod?
I created this mod mostly out of a desire to allow myself and other modders to exert more control over the movement speed of the player. Without these fixes, modifying the "SpeedMult" Actor Value is very treacherous. First of all some effects don't apply when you would expect them to (since Skyrim doesn't recalculate movement speed whenever this value changes). This has been fixed by several other mods already. However there is a second problem, which can cause results to be very unpredictable when multiple slowing effects are active.
For instance, if two effects with a slow of 50% are active, the target will actually not be slowed at all. However add a third effect that slows the target by 25%, and now they will be slowed by 75%. The reasons for this are as follows:
-
[](Most) slow effects stack on top of each other.
[
]SpeedMult represents a percentage, and the default value is 100.[]A value of 0 for SpeedMult is considered to be equal to 100.
[]Negative values are treated the same as positive values.
In the above situation, after the third effect is added, SpeedMult is equal to -25. The game treats this the same as if it were 25, meaning the applied slow is equal to 100 - 25 = 75%.
If SpeedMult modifiers don't stack, the value of SpeedMult in the same situation never goes below 50. The strongest effect will win, and the rest are ignored. As long as every individual effect has a magnitude of less than 100 (which is the case in vanilla).
This means that if you apply for example an 80% slow to the player, you know they will always be slowed down by at least 80%, and they will only be slowed more than that if an effect with a greater than 80% slow is applied as well.
Things this does not fix
SpeedMult values can still go below 0 when the effects are combined with magnitude increases from Potions of Destruction, or similar effects added by mods. This is a more complicated problem to address.
Simply Capped Slow by Rafear attempts to provide a fix for this issue, however at this time it's not compatible with this mod. If there is some interest, I will create a patch.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 389 endorsements and over 55k downloads.
- Solves a real annoyance—slows that don't work or stack weirdly.
- Makes other mods that tweak speed work better, which is a big plus for modded playthroughs.
⚠️ Cons
- Last updated in 2021, so it might not be compatible with the latest Skyrim versions or mods.
- Could conflict with other mods that alter SpeedMult or slow effects, so check your load order.
- Niche fix—if you don't use slow effects or speed mods, you might not notice a difference.
For Skyrim players who use mods that rely on SpeedMult or slow effects and want those to work reliably. Also for anyone annoyed by glitchy slow effects in combat or magic. Skip if you play vanilla or don't care about speed mechanics.
💡 Beginner Tips
- Place this mod early in your load order to ensure its fixes apply before other mods.
- If you use a mod manager like Vortex or MO2, let it handle the file placement to avoid overwriting issues.
- Test with your speed-modifying mods to confirm they work as intended after installing.
