About this mod Author’s original text
ReefPortals — Cross Server Portals Continued, The Reef build
A build of Cross Server Portals Continued by jcruse03 (itself the Valheim 1.0 continuation of lunarbin's Cross Server Portals), licensed GPL-3.0. Same plugin GUID (lunarbin.games.valheim) and version as upstream 1.3.1, so a client on this build pairs with a server on the upstream one and vice versa.
What it does
Tag a portal Source|host:port|Target and walking through it logs you out and joins that server, putting you out of the portal whose tag (or source tag) is Target. Glyphs turn green on such portals. Ordinary portals are untouched.
What The Reef changed
One thing: a 4th tag field carries the destination server's password.
main|203.0.113.5:2458|nursery|the-nursery-password
When the portal joins that exact host and port and the server asks for a password, the field is supplied to the game's own password step; no dialog. The password is only ever used for the server the portal points at (a later manual join to another server gets the normal dialog). It is written nowhere else than in the portal tag you typed. This is meant for private servers among friends, where the password is shared anyway: anyone who can read the portal tag can read the password. If that is not acceptable for your servers, use the upstream mod with PortalPass instead.
Everything else — PreserveStatusEffects, glyph and effect colours, PromptBeforeTeleport, RequireAdminToRename (ServerSync) — is upstream, unchanged.

Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
