Aura Effects for Pathfinder/3.5E
In order to support some homebrew stuff I have converted kentmccullough's 5E Aura Effects extension to work with 3.5E/Pathfinder.
You can find a simple explanation of how the extension works in the README.
Edit: realized I should mention I've tested this extension with v4.0.10 and shouldn't work with any versions before v4.0.7 as that was the earliest that the getDistanceBetween function was added.
Edit
I've been collaborating with bmos on his repo for subsequent changes. Releases can now be found here: https://github.com/bmos/FG-Aura-Effect/releases
Also you can find them mirrored to the Nexus at: https://www.nexusmods.com/fantasygroundsunity/mods/2
