Reneer's Knock Out Arrows 1.2 mod.
This mod creates a new arrow type called 'Knock Out Arrow.' It does exactly what it says: it knocks out NPCs. However due to giving the NPC a nap, it also has the effect of bringing the NPC's health back up to full. These arrows can be used with any bow, enchanted or not.
These arrows will only be effective if the intended target does not see the arrow coming at them (basically either you are far enough away that they can't see you, or their back is turned.)
Change Log:
1.2 - Fixed some errors in Detection. Now you just have to be behind or close to 90 degrees on either side of your target. This avoids Oblivion Detection problems (hopefully.) 1.1 - Fixed problems with NPCs selling the arrows. 1.0 - Changed some code to make the mod more stable, added in Detection so that you can't knock out NPCs that are aware of your prescence.
0.95 - Added a major change: now instead of knocking out for 15 seconds, the knock out period is determined by skills, and can range anywhere from 5 to 25 seconds. [Don't worry about the enchantment being only for 1 second.]
0.94 - Made mod more compatible with other mods. (Removed mod conflicts)
0.93 - Creatures / Guards / NPCs will now chase you after 15 seconds if you were detected while using the arrows.
0.92 - Fixed CrimeGold bugs.
0.91 - Fixed some minor bugs in the script. Changed some things in the Readme.
0.9 - Initial (BETA) release.
