Introduction
Damage Threshold, or simply DT, is the mechanic introduced in Fallout: New Vegas in addition to damage resistance DR. This is a plane number subtracted from incoming damage before DR is applied. It allowed to even completely negate damage if it is lower than your total amount of DT, so weak weapons like 10mm won't hurt you at all when wearing power armour for example. And it works for both the player and enemies wearing armour. Unfortunately Bethesda removed it in Fallout 4, but thanks to Shavkacagarikia and his Damage Threshold Framework this mechanic is brought back.
The only problem is adding it to existing and modded armours. It would require support from all mod authors who create new or modify existing armous (which is unlikely to happen) and result in insane amount of compatibility patches.
The another more universal approach is to create a global dynamic patch for load order of user to calculate and add DT to all armours automatically, for any existing and future armour mods. This is where this patcher comes in.
Damage threshold patcher is a script for FO4Edit that creates ESP patch plugin to add DT values to armours and creatures, DT is calculated this way
Simple Armor : DT = DR fDTMult + iDTAdd
Powear Armor : DT = DR fDTMult iPAMult + iDTAdd
NPCs : DT = DR fDTMult fDTMultNPC
OMODs : DT = DR fDTMult iModMult
Spells : DT = DR fDTMult + iDTAdd
Ingestibles : DT = DR * fDTMult + iDTAdd
DR - average of all damage resistances of armor greater or equal than the armor rating and iDRMin
fDTMult - multiplier, the result is
This utility automatically calculates and assigns Damage Threshold (DT) values to armors and unarmored NPCs across all mods, bringing back the classic Fallout: New Vegas DT system. It's a must-have for players who want that old-school damage reduction in their modded game.

💡 Beginner Tips

- Check if your other armor mods have built-in DT support to avoid double-dipping.
