Penumbra VS XivAlexander

you need penumbra if you don't have it yet and use that to install the mod

You can find various body edits on https://www.xivmodarchive.com/ . In order to use them, the easiest way is to use the XIVLauncher (https://github.com/goatcorp/FFXIVQuickLauncher) which enables the addon system. With that, download the addon "Penumbra" to use those edited bodies ingame (https://github.com/xivdev/Penumbra).

Runtime loader (Custom clothes, animation): https://github.com/xivdev/Penumbra (a year old)

You'll need Penumbra, which in itself requires Dalamud ala the FFXIVQuickLauncher tool. You can install FFXIVQuickLauncher via an installer and here's a video for installing Penumbra.

Download that, also download textools https://www.ffxiv-textools.net/ OR penumbra https://github.com/xivdev/Penumbra (this one also needs XIVLauncher) and then import the file you downloaded from nexusmods, and that's it.

Penumbra

Penumbra is a quicklauncher plugin (link) that allows you to non-destructively apply mods.

From what I understand that was fixed a few versions ago. https://github.com/xivdev/Penumbra/releases/tag/0.4.6.7

Should be this one I think.

The issue with this is that lag and ping even on a "good connection" isn't like what it is with the Japanese servers so it's way harder and sometimes has even been impossible to completely avoid drift. There are plugins that fix the issue but they're obviously not officially endorsed.

https://github.com/Soreepeong/XivAlexander found it. idk how it works tho

XIVAlexander (Ability Cooldown Manipulation): https://github.com/Soreepeong/XivAlexander

either way should work but just checking this https://github.com/Soreepeong/XivAlexander/releases might just be the easiest

Per the website: https://github.com/Soreepeong/XivAlexander

Try out xiv alexander, https://github.com/Soreepeong/XivAlexander. It'll essentially remove the animation lock which will give you 0 latency, but due to the way it works it is a ban-able mod so use it at your own risk. However, I've been using it since shb and I haven't heard anyone get banned over it either.
