This mod requires the following mods to function
ValheimModding-Jotunn
Jötunn (/ˈjɔːtʊn/, 'giant'), the Valheim Library was created with the goal of making the lives of mod developers easier. It enables you to create mods for Valheim using an abstracted API so you can focus on the actual content creation.
Preferred version: 2.30.2
denikson-BepInExPack_Valheim
BepInEx pack for Valheim. Preconfigured with the correct entry point for mods and preferred defaults for the community.
Preferred version: 5.4.2351README
Rotheart
The swamp takes its tithe. Carry a living ooze heart in a rusted iron cage: resist poison, then spend adrenaline to unleash a miasma that hurts nearby creatures much more than it hurts you.
Rotheart adds one original swamp-tier trinket, with a Blender-made model, inventory icon, visible hip attachment and sparse green aura particles.
Tested in a disposable native Linux client. Remote multiplayer and dedicated servers are unverified. Use a separate profile and back up your saves before adding custom items.
Crafting and use
Craft one Rotheart at a level-one forge after discovering its ingredients:
| Material | Amount |
|---|---|
| Ooze | 10 |
| Guck | 5 |
| Entrails | 5 |
| Iron | 5 |
Equip it in the native trinket slot. It weighs 2, has one quality level and does not drain durability. Valheim currently labels this category “Utility item” in the tooltip; Rotheart does not occupy a weapon slot.
| Effect | Behavior |
|---|---|
| Passive protection | 50% less poison damage while equipped |
| Activation | Native combat actions fill a 10-adrenaline meter; reaching full automatically consumes it |
| Active miasma | Lasts 10 seconds, with a 6-metre radius |
| Every two seconds | Lose 1 health, and deal 12 base blunt damage to each eligible nearby creature |
| Health floor | Rotheart's health cost cannot reduce you below 1 HP |
A complete activation gives five pulses: 5 wearer health versus 60 base damage per target. Native creature resistances and world difficulty still apply. The green miasma deals blunt, not poison, so it remains useful against poison-immune swamp creatures.
- Other players, tamed creatures, friendly factions, structures and terrain are excluded, even with PvP enabled. Native hostile factions and wild animals can be hit.
- The radius is spherical and does not require line of sight.
- No extra hotkey or separate charge resource. Adrenaline capacity returns to normal when unequipped.
- Filling adrenaline again refreshes the duration and restarts the pulse timer; it does not stack another aura.
- Unequipping or dying stops the active aura. Unequipping also removes the passive resistance. Teleport/cutscene frames do not deal aura damage.
- Stronger native poison-resistance mead keeps its stronger protection; reductions do not multiply.
Requirements and installation
Built and tested against Valheim l-1.0.20, Unity 6000.0.75f1. Older versions without native trinket/adrenaline APIs are unsupported.
Required dependencies:
- denikson-BepInExPack_Valheim 5.4.2351
- ValheimModding-Jotunn 2.30.2
Mod manager: install Jarki-Rotheart into a separate Valheim profile and accept both dependencies. Launch modded through your normal OS-appropriate loader route.
Manual: close Valheim, install the required dependencies, then copy this archive's plugins/Rotheart/ directory into BepInEx/plugins/. The resulting plugin path is BepInEx/plugins/Rotheart/Rotheart.dll. Keep LICENSE and remove duplicate Rotheart DLLs. Model, icon and effects are embedded; no additional asset downloads are needed. Native Linux uses Linux Doorstop, not Proton DLL overrides.
The mod declares matching installations on the server and every client because it adds a networked item. This requirement is not a claim of verified remote-multiplayer compatibility. Windows, controllers, unrelated-mod combinations and every armor outfit have not been tested.
There are no gameplay configuration options in this release. Stable plugin ID: jarki.rotheart; item prefab: Rotheart.
Uninstall and troubleshooting
Back up first. Remove Rotheart items from characters, chests, drops and displays before disabling or uninstalling the mod. Loading a save without its custom prefab definition can lose those items. Then close Valheim and remove BepInEx/plugins/Rotheart/Rotheart.dll. Uninstall/reinstall has not been runtime-tested.
If the item is missing, confirm that both dependencies loaded and that your game supports native trinkets. Learn all four ingredients and use a sheltered level-one forge. For errors, report your game/mod/dependency versions, reproduction steps and relevant redacted BepInEx/LogOutput.log entries. Never publish saves, account identifiers, passwords or tokens.
Verification and credits
The exact gameplay DLL completed 65 in-game assertions, including fixture prerequisites: real forge crafting and ingredient consumption, native equipping, poison resistance and stronger-mead precedence, 9-versus-10 adrenaline activation, meter consumption, five timed pulses, actual hostile health loss, draugr/blob damage, exclusions, the nonlethal floor, refresh, unequip/death cleanup and actual character-file save/load into a fresh Player. Final scenario: zero Unity errors or exceptions. Inventory/tooltip, hip attachment, colored world drop and aura-combat screenshots were inspected.
Release packaging verifies that the ZIP contains the same runtime-tested DLL. This is not a fresh mod-manager ZIP-import test, a two-client network test or a dedicated-server test. Release builds retain two existing MSB3277 framework-reference warnings; they are not suppressed.
