PotionDuration

Potions, brews, elixirs and imbuements (weapon coatings) last as long as you choose instead of the base game's 60 minutes. The mod default is 2 hours.

Only the 60-minute potions, brews, elixirs and imbuements change. Healing potions and brews, Vermin Salve and every other consumable keep their base-game timing.

What changes

Group	Items	Setting
Potions and brews	Fire Resistance Brew, Minor Sun Resistance Brew, Garlic, Holy and Silver resistance brews and potions, Brew of Ferocity, Potion of Rage, Enchanted Brew, Witch Potion, Wrangler's Potion	PotionMinutes
Elixirs	Elixir of the Bat, Beast, Blasphemous, Crow, Prowler, Raven, Twisted and Werewolf	ElixirMinutes
Imbuements (weapon coatings)	Blood, Chaos, Frost, Illusion, Storm and Unholy Coating	ImbuementMinutes

The buff icon's timer and the tooltips (on the item in your bag and on the buff icon) show the new time.

Installing

Requires BepInExPack V Rising.

• Server: install PotionDuration on the server. This is what makes the effects last longer. On a dedicated server, copy PotionDuration.dll into BepInEx/plugins/ while the server is stopped, then start it.
• Players: install PotionDuration with your mod manager (r2modman or Thunderstore Mod Manager). This is optional: it makes the tooltips show the new time. Without it everything still works, but the tooltips say 60 minutes, and the imbuement's buff icon shows no timer while more than 60 minutes are left (the base game's icon can't show more than 60).

The same mod goes on the server and on each player's game.

Settings

The config file BepInEx/config/PotionDuration.cfg is created the first time the game or server starts with the mod. In r2modman you can edit it under Config editor.

Setting	Default	What it does
PotionMinutes	120	How long potions and brews last, in minutes
ElixirMinutes	120	How long elixirs last, in minutes
ImbuementMinutes	120	How long imbuements (weapon coatings) last, in minutes
Enabled	true	Set to false to turn the mod off

Choosing a duration (the base game is 60 minutes):

Minutes	Duration	Compared with the base game
30	30 minutes	50% shorter
120	2 hours	100% longer (twice as long), the default
240	4 hours	300% longer (4 times as long)

Any value from 1 to 1440 minutes (24 hours) is accepted. A value outside that range is set to the nearest limit.

Players: use the same minutes as the server. The tooltips show your own setting, so if it differs from the server's, the tooltip is wrong (the effect itself always follows the server).

Changes apply the next time the server or game starts. A potion or imbuement that is already active keeps the duration it started with.

Advanced settings

Setting	Default	What it does
Include	(empty)	Comma-separated buff names to treat as potions too (or as elixirs, if the name contains "Elixir"). The buff must last 60 minutes in the base game
Exclude	(empty)	Comma-separated buff or imbuement (weapon coating) names to leave unchanged
DumpBuffs	false	Writes every timed buff (name, ID, duration) to BepInEx/config/PotionDuration/buffs.csv, to find buff names

Good to know

• Only one elixir can be active at a time, as in the base game.
• Players with the mod see their own setting in the tooltips on every server they join, including servers without the mod.
• To check it works, look in BepInEx/LogOutput.log for 21 buff prefabs changed and 6 imbuements (weapon coatings) changed (server) and tooltips: 48 duration values changed (player).
• A game update can rename buffs. If the server log says 0 buff prefabs changed, the mod needs an update.
• To remove the mod, uninstall it in your mod manager, or delete PotionDuration.dll (and PotionDuration.cfg) and restart.

Credits

• Project setup (BepInEx packages and NuGet feeds) modelled on ScarletBrazier by markvaaz; its change to braziers' burn time also gave the idea of changing a duration in the game's own data.
• The "server has finished loading" hook (a Harmony postfix on SpawnTeamSystem_OnPersistenceLoad) is a common pattern in V Rising mods, e.g. KindredCommands by odjit, ScarletCore and Bloodcraft by zfolmt.
• Built with BepInExPack V Rising (BepInEx, HarmonyX, Il2CppInterop).

No code was copied from these mods; thanks to their authors for showing the way.

This mod was made with Claude Code, Anthropic's AI coding assistant. Claude worked out how the game stores potion and imbuement durations and tooltip text, and wrote the code and documentation; I decided what the mod should do, reviewed the changes, and tested each version in game on my own server.

Made for V Rising 1.1.15 with BepInEx 6 (BepInExPack V Rising 1.733.2).
