Which addon is Acuity?
An in-game error, a load-order warning or a red Dependency line that mentions
user:/AddOns/Acuity/ — or a folder sitting in your
Documents\Elder Scrolls Online\live\AddOns\ that you do not recognise — belongs to what
is listed below.
Anchors for every claim on this page: the live game runs API 101050 (Update 50, live 2026-06-08). Update 51 is on the public test server now and is scheduled to go live on PC/Mac on September 28, 2026. Feed retrieved 2026-08-22 · corpus snapshot 2026-08-22.
2 addons in the ESOUI catalogue ship a folder called Acuity, so the folder name alone does not settle it. The standalone one — the copy its own author publishes and updates — is Acuity; the others bundle a copy of it inside their own download. The game loads exactly one folder of a given name.
| Addon | Relationship to this folder | Downloads, lifetime | Status |
|---|---|---|---|
| Acuity | ships it as its own addon | 22,019 | not updated since the patch |
| Acuity Deadland Fix | ships it as its own addon | 3,554 | not updated since the patch |
How to read the error line
An ESO Lua error is written as
user:/AddOns/<Folder>/<File>.lua:<line>. Only the
<Folder> segment identifies the addon — the file name and the line number are internal to it,
and the addon's display name in the add-on list is frequently different from its folder name. That is the
whole reason this page exists.
