📋 About This Mod

Chemistry Sets are neat, and mods like No More Useless Chemistry Sets - ESPless add more of them to the world, but they are basically free meds and chems. The idea behind this mod is that they should require investment if they are going to be used effectively. Essentially, if you have no science skill, no medicine skill, and are dumber than a box of rocks (1 INT), how the hell do you know how to create perfect stimpaks? This is immersion breaking, makes no sense, and is no risk high reward.

This mod adds more use to both science and medicine, as well as a little bit of INT and Luck, by making them required to be able to produce meds and/or chems. Changes include the following:

  • []Can attempt to create medicine or drugs at any skill level[/]

    []Creation can fail

    a. Formula is (Science + Medicine) (INT/10 + Luck/20)

    b. Formula must come out to 50 or more to succeed (at 5 INT and Luck, requires Science + Medicine to be 67)[/]

    []If success, you get between 1 and 6 items based on the formula evaluation.[/]

    []If making meds, you can get stimpaks, medx, radx, or radaway.[/]

    []If making chems, you can get psycho, buffout, mentats, rebound, or steady (all vanilla options)[/]

    []The actual items you get on success are random within the respective list.

    Best use of this plugin is to merge it with other stuff so you aren't using a plugin slot for it.

    Incompatible with anything that changes GSChemistrySetScript or NVDLC03ChemistrySetSCRIPT

    1. 1. 0 Utilizes Keywords and JIP for easier user customization to the meds/chems you can produce. I have left 1. 0. 1 up in Optional Files in case anybody doesn't want to use JIP or Keywords (both of which are mods you should already have anyway tbh).

📊 Pros & Cons

✅ Pros

  • Solid download count (70,757) shows real interest, even if endorsements are modest.
  • Simple concept: Chemistry Sets now scale with your stats, so crafting keeps up with your build.
  • Lightweight gameplay tweak that doesn't overhaul the whole crafting system.

⚠️ Cons

  • Only 74 endorsements compared to downloads—could be a sign of mixed reception or just quiet users.
  • Last updated April 2026—might not be compatible with future game patches.

💡 Beginner Tips

  • Since it's a simple rebalance, you can install it mid-playthrough, but make a save before just in case.
  • Check if you have other mods that alter Chemistry Sets—they might conflict.
  • If you're using a mod manager, let it handle the file placement to avoid overwriting.
