JavaScript Extensibility API

We provide an official scripting engine and extensibility API as part of the symbiote module that gets loaded into the client. We have the freedom to define the API shape in whatever way we like. The ultimate goal is that players should never have to resort to network interception or memory manipulation to do legitimate modding.

This scripting engine is based on ClearScript. The choice of JavaScript is deliberate; the TERA community is already quite familiar with it due to TERA Proxy and TERA Toolbox historically being based on it.
