Ephervex / Instances

What Ephervex does

Create an environment and inspect a failure.

Set up the conditions you need without filling your everyday launcher with test instances.

Mod isolation

Test smaller mod groups while Ephervex keeps known required dependencies together.

Temporary instances

Use a temporary instance for a quick reproduction, or make it persistent when you need to return to it.

Logs and diagnostics

Inspect logs, crash reports, diagnostics, and snapshots from the desktop or command line.

Desktop interface

Preview the desktop tools, then open the guides for the full workflow.

Manage mods

Browse compatible mods, review dependencies, and isolate a failure in a large mod set.

Linked servers

Run a server beside a client and inspect its console when the problem crosses the connection.
