Unless I am mistaken, the Slow Time effect does not work if used by NPCs. I'd rather be wrong, but just in case, how would you make a Slow Time AND a Time Stop effect that would work against the player, usable by NPCs?

Il Ducey (thanks again mate) has already made something good I think

Scriptname TimeStop extends ObjectReferenceActor Property PlayerREF autoImageSpaceModifier Property QuaranirWhite autofloat CurrentSpeedfloat CurrentWeapSpeedevent WhateverEventYouWantToBeginThisSequence()	QuaranirWhite.Apply()	CurrentSpeed = PlayerREF.GetAV("SpeedMult")	CurrentWeapSpeed = PlayerREF.GetAV("WeaponSpeedMult")	 PlayerREF.DamageActorValue("SpeedMult", CurrentSpeed)	 PlayerREF.ModActorValue("CarryWeight", 1)	 PlayerREF.DamageActorValue("WeaponSpeedMult", (CurrentWeapSpeed +- 0.05))endEventevent WhateverEventYouWantToEndThisSequence()	  	 QuaranirWhite.Remove()	  PlayerREF.RestoreActorValue("SpeedMult", CurrentSpeed)	  PlayerREF.ModActorValue("CarryWeight", -1_	  PlayerREF.RestoreActorValue("weaponspeedmult", (CurrentWeapSpeed +- 0.05))endEvent

but I still would like more opinions/solutions.
