Tempest

Version 0.1.15. Requires Crucible 0.3.30 / Crucible.UI 0.3.21. Changes are in CHANGELOG.md.

Rare dangerous weather: blizzards in the lowlands and the Deep North and severe thunderstorms, announced five minutes ahead and the same for every player.

Features

• Rare blizzards in the Meadows and Black Forest that freeze the unprepared as the Mountains do. In the Deep North a blizzard is a whiteout: the twilight snowstorm with thicker fog and full wind, under the same warning, notice and Cairn badge.
• Severe thunderstorms that drive ground lightning across the lowlands and the sea. Player bases are spared from lightning.
• Every event is announced five minutes ahead. With Cairn installed, the warning also shows on Cairn's weather HUD.
• The server decides the weather, so every player sees the same event at the same time, and an event survives a restart.
• Weather filter: the server can switch off individual game weathers.
• Tempest events never occur in the Mountain or Mistlands, and only a blizzard reaches the Deep North. Biome settings drop names a kind does not cover, and the server log says so once. An existing host config keeps its saved Blizzard Biomes; add DeepNorth there to get the whiteout.
• Tempest yields to the game's own raids and random events: no new event starts over a player inside one, and players inside one get no Tempest strikes, hazards or messages while the raid's sky shows.

Requirements

• BepInExPack Valheim 5.4.2351
• Jotunn 2.30.2
• Crucible 0.3.30 or a later 0.3.x, which includes Crucible.UI 0.3.21 (the shared Meadworks interface kit)

Installation

• Mod manager (recommended): install Tempest with r2modman, Gale or the Thunderstore Mod Manager; the dependencies above are installed for you.
• Manual: install BepInExPack Valheim, then Jotunn and Crucible, then copy the plugins/Tempest folder from this package into BepInEx/plugins/.
• In multiplayer, install Tempest on the server and on every client (see Multiplayer).

Configuration

• Settings file: BepInEx/config/com.meadworks.tempest.cfg. Edit it in game with Almanac (the Meadworks settings book) or any ConfigurationManager.
• In multiplayer the server's values win for weather settings and admins can lock settings; locked settings show as read-only.
• Cheats: Weather Commands (summon or stop an event) and Personal Weather Override, both off by default. In multiplayer they stay locked unless the server allows them.
• Converter: imports NoFogBruh's weather switches into the weather filter after a preview, from Almanac's Convert tools or the console (tempest import previews, tempest import apply imports). Host or single player; Tempest's settings file is backed up first.

Multiplayer

• Required on all peers: install it on the server and on every client, same major.minor version, so the weather matches on every machine.
• Joining a server without Meadworks: Crucible waits for the server's reply (10 seconds by default), then treats it as a vanilla server; Tempest turns off for that session and cheats stay locked. Tempest also turns off on a Meadworks server that does not run Tempest.
• Players without Meadworks (vanilla clients) cannot join a server running Tempest. With only server-only or client-optional Meadworks products installed, an admin can let them join with Crucible's Network.AdmissionMode set to AllowVanilla.

Compatibility

• Steps aside, module by module, and notes it in the log: WildWeather turns off Tempest's weather events; NoFogBruh turns off the weather filter; Valheim_Admin_Tool turns off the personal weather override.
• Converter imports: NoFogBruh's weather switches.
• Optional Meadworks integration: Cairn shows Tempest warnings on its HUD.
• Solstice is optional: seasonal weather names use their base filter rules, and host-owned seasonal weights can adjust ordinary weather. Empty defaults keep existing weights. Tempest owns weather selection and events; Solstice owns season facts. See the season contract, including Cairn forecast limits.

Notes

• Gamepad: supported through the shared Crucible.UI controller navigation and configurable pad chords.
• Languages: English, Spanish, Simplified Chinese, Russian, French, German and Korean (non-English text is machine-assisted).
• Inspired by / replaces (behavior reimplemented, no code reused): WildWeather (SirJose).
• Listed under Thunderstore's AI Generated category; tested in-game.
