I created a standalone mod for the Electric Harpoon, a special weapon used in the companion NPC mod series I'm currently working on
https://steamcommunity.com/workshop/filedetails/?id=3649016146
with modifications for human players.
Although it has been weakened to some extent, it is still extremely powerful, as it can reliably kill the enemy if you get the first move in a 1v1 battle. It is not recommended for use in PVP or traitor mode.
The condition for the lethal slip damage to continue is to maintain the harpoon cable connected, so it's not particularly effective against multiple enemies. Still, being able to reliably neutralize a small enemy is a major advantage in multiplayer.
