I made this mod because normally in vanilla after 15 seconds the NPC will heal itself back, meaning if you have a lot of followers it can be very OP.
This only changes duration up to 4 minutes.
In vanilla, your follower will recover from bleedout faster when they have recovered enough health, you can speed this up by casting healing spells, use a mod that allows you to give potions, if you end combat, or fast travel.

This is a simple mod that edits only one record.


Incompatible:
Nether's framework has it's own bleedout system which overrides this.
