Please see the FORGE for the latest version.

AoE Effects – Now Available!

After a major overhaul and extensive testing, we’re proud to release AoE Effects v1.0 — the next evolution of the popular Aura Effects extension.

AoE Effects expands far beyond simple auras. It is now a powerful and flexible Area of Effect management tool for Fantasy Grounds, giving GMs precise control over how effects are applied based on token proximity and shape.

Key Features

• Multiple Shape Support — Spheres, Cylinders, 3D Rectangles (including Cubes), and now full Cone support with adjustable angles and orientation.
• Smart Token Detection — Choose exactly how auras trigger with the new Token Overlap Behavior setting (Center, Quarter, Near Edge, or Edge).
• Global Aura Adjustment — Fine-tune every aura in your campaign at once using the new Aura Size Adjustment option (in feet).
• Advanced 3D Calculations — Accurate height-aware detection for cylinders, cubes, and cones.
• Performance Focused — Efficient token tracking and movement filtering to keep games running smoothly.

What’s New in v1.0

• Official name change from “Aura Effects” to AoE Effects to better reflect its expanded capabilities.
• Full support for Cone shaped effects.
• New GM options for controlling aura triggering behavior and global size adjustments.
• Improved accuracy and internal tweaks (especially for Edge-based cubes).
• Cleaner architecture and better long-term maintainability.

This extension is compatible with D&D 5E, D&D 4E, D&D 3.5E, PFRPG, PFRPG2, SFRPG, and SFRPG2.

We’d like to thank everyone who contributed to the original Aura Effects extension, as well as the community members who helped test and shape this major update.

Feedback, bug reports, and feature suggestions are all welcome in this thread.

If you are looking for the old Aura Effects forum thread you can find it here!

I just downloaded the new version and it's giving an error when launching a campaign:

[6/9/2026 9:31:14 AM] [ERROR] Unable to locate extension file. [AoE Effects] [/strings/strings_aura.xml]

This happens on a new, blank campaign with no other extensions. Once the campaign loads, the extension effects don't actually work.

Delete the old one and update again and it should fix it. I uploaded a new build.... a trailing / was the cause.

Indeed, it's fixed and it works now, thanks.

Disabling Aura Effect Chat Messages

You can suppress aura apply/removal notifications for specific factions or all factions by adjusting the “Silence Notifications for Aura Types” setting.

I can't find that setting in the Options window though, where is it available?

Thanks for all the work you put into this and keeping this running and adding in good stuff. Thanks!!!!!

I noticed there were AoE effects, one using the old Aura effects thumbnail and the newest one with the banner you have in your op. Are they both the same?

They are identical, it is a glitch that is causing both to show in the Forge, it has been reported to Moon Wizard.

That was left over coding from the old Aura Effects, looking into that issue.

In case anyone wants some examples I use in my GAL extension - these show different AURA shape uses - look between "AURA:" and the following ";" skipping any colors which was for some other extension I don't even use (lot of BCEG effect syntax you can ignore).. FYI a lot of default arguments taken advantage of - and I'll be danged to hockey sticks if I ever use that misnamed misbegotten "cube" keyword that is really an orthogonal 2D flat square. Most of these are also designed to not be placed at 0 degrees but instead respect the tokens orientation.

Thanks for that list @SilentRuin, that is very helpful.

We are already hard at work, on correcting the "cube" issue that is present in the extension that was left over from the old Aura Effects coding.

The logic that we will be using for version 2 of this extension will address the issue and make cubes, well cubes (3 dimensional), and squares will be flat.

- default will stay sphere (3d)
- circle (flat, no height)
- cylinder (3d)
- square (flat, no height)
- cube (3d)
- wall (3d)
- Line (flat, no height)

But that is down the road a bit, trying to get beyond the version 1 release at the moment.
