An Add-On for defining which Mirror to use for 5e Tools. Comes with the primary website, as well as two known mirrors. You can also set it to custom and use your own hosted version of 5e Tools. This is primarily meant to be used with VTTs such as FoundryVTT where images, links, and content might get broken if 5e.tools is down.
