This mod adds a poison designed to pickpocket poison and silent assassinate NPCs.If you successfully place this poison in an NPC's inventory, no conflict will be triggered after he/she dies, unlike normal hand-crafted poisons.This mod also adds a zero-damage non-hostile standalone Daedric bow and arrow.You can apply this poison to the bow and use it to poison NPCs from distance.
This poison slowly damages NPCs' health and give them a painless death.In lower levels and lower difficulties, the effect of this poison is almost immediate, while in higher levels it takes some time (almost 50 seconds to kill a Whiterun Guard with a leverl 251 Character and legendary difficulty ) to kill the target.
The effect of this is poison is not reduced by the target's resist to poison.
Shooting with the bow or pickpocket poisoning an NPC with this poison is not a crime and it can be done right in front of the guards.
The only factor determining the time it takes to kill a target is his/her base health plus fortify health enchantments.
To add these items and the poison to your character you can type the following lines in the console:
help "daedric bow of the silent assassin"
help "daedric arrow of the silent assassin"
help "mercy of sithis"
I suggest you download this mod too because it increases the chance of successfully poison pickpocketing.
