This is a re-upload of Particle Arrow Replacer by Ghostnull, since it is no longer available anywhere. The plugin adds unique particle effects to all enchanted arrows in Morrowind, Tribunal, and Bloodmoon.

Below is the original ReadMe:

*****************************************************************
     The Elder Scrolls III  MORROWIND: 
     Particle Arrow Replacer
     Version 4.0

*****************************************************************
     1. Installation
*****************************************************************
If using a any previous versions of Particle Arrow Replacer, 
uninstall them first.

To install the plugin, unzip the files into the Morrowind/Data 
Files directory. Requires both Tribunal and Bloodmoon to play.
Activate the "Particle Arrow Replacer.esp" and play!

If the Official Area Effect Arrows plugin is also being used, or 
another mod that uses or changes Area Effect Arrows (for example, 
Redesigned Vivec), load AEA-Compatibility.esp after Particle Arrow 
Replacer.esp and Area Effect Arrows.esp

AEA-Compatibility.esp just alters the references for the arrows 
and bolts in Area Effect Arrows unlike previous versions were the 
full Area Effect Arrows mod was included. This was done increase
compatibility.

*****************************************************************
2. Playing the Plugin
*****************************************************************
Just play the game normally and enjoy! The .esp replaces every
original enchanted arrow in the game, including ones from the 
expansions. 

*****************************************************************
3. Compatibility
*****************************************************************
As this mod alters the references for the arrows, it will conflict
with mods that also alter the arrows such as rebalancing/pricing 
mods. You will need to "merge objects" from confliction mods 
together with tools such as TESTool or Wrye Mash. Refer to the 
ReadMe's of the respective tools for instructions.

*****************************************************************
4. Save Games
*****************************************************************
This will not invalidate your old saved games. It's always a good
idea to clean your save games though when installing/removing mods.

*****************************************************************
5. Notes
*****************************************************************
Feel free to use these arrow meshes however you see fit.
Please email any comments, suggestions, or questions regarding this
plugin to [email protected]

*****************************************************************
6. Known Issues
*****************************************************************
There is one known problem. When viewing in third-person/vanity
mode and you have an arrow or bolt readied and start moving, the 
particle effect will become dislodged from the arrow or bolt. It's
just an engine limitation/bug with particle effects, similar to 
Trueflame and Hopesfire with the odd angles the particles sometimes 
point.

This graphical issue is fixed with Morrowind Code Patch.
This mod can not and will not ever affect self-enchanted arrows or
bolts. It's a limitation and sure impossibility of the engine.
