## Summary

**Last documented edit**: Feb 09 2024 by [mana vortex](https://app.gitbook.com/u/NfZBoxGegfUqB33J9HXuCs6PVaC3 "mention")

Changing item stats happens by making changes via **TweakXL** or **REDmod** in the [tweaks](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/tweaks/tweaks "mention").

## How to edit tweaks?

You can change tweaks with

* REDMod (see [changing-npcs-tweak-edit-redmod](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/core-mods-explained/tweakxl/tweakxl-changing-game-records/changing-npcs-tweak-edit-redmod "mention"))
* Cyber Engine Tweaks (see Scissor's tutorial ([Google Doc](https://docs.google.com/document/d/1pPN_RiluE-4PwGWOxdEVOegfBEaEsd5APHndr82FdPo/edit)))
* TweakXL (see [changing-vendor-inventory](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/core-mods-explained/tweakxl/tweakxl-changing-game-records/changing-vendor-inventory "mention"))

<summary>Why? What's the pros and cons for each?</summary>

[psiberx says](https://discord.com/channels/717692382849663036/953004282142163014/1177462646937763850):

it's mostly preference but there are real advantages of TweakXL:

* proper record creation and cloning with all properties
* proper hot reload with rolling back to initial state, and not just reapplying your mod changes on top of previous run
* it's much faster when used for declarative tweaks and even for scripts (I did some optimizations for CET which reduced loading times 20x, but it needs more; for reference if we convert just the existing clothing mods to CET it'll increase game launch time in minutes)
* easier to work with arrays
* can create new stats

REDMod can do the same, but doesn't offer you [hot reload](https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/modding-tools/redhottools/rht-hot-reload) features.

## Removing properties

If you want to **safely delete** a record property, set its value to **None**.
