FrostmourneHungers

By demolishandrock, published by Ashwardens. Version 1.2.3.

A cursed sword found in the Deep North. Upgrade it at the Black Forge and Forge of Potential, gain speed while carrying it, and collect souls to unleash a deadly frost wave.

The sword

• One pedestal is generated per world. Frostmourne cannot be crafted, and the pedestal does not refill once claimed.
• Pulling it requires 300 current health. Anyone below that threshold receives the Unworthy curse and dies; the sword stays on the pedestal.
• Tier 1 deals 215 Slash, 120 Frost, and 80 Spirit damage.
• The wielder curse grants 10% more movement speed and 25% faster attacks while the sword is held or sheathed on your back. Simply storing it in your inventory does not grant the curse.
• Includes a custom sword, carved stone pedestal, blue glow, and icy mist. The models are embedded in the plugin; no extra asset download is required.

Soul power and special attack

A blue Soul Power bar appears on the right side of the screen while you hold Frostmourne. Each qualifying enemy kill credited to you while holding it adds 2%, up to 100%. The power stays with the sword through normal saves, transfers, death recovery, and upgrades; it does not decay.

Use the sword's normal secondary/power attack:

• Below 100%, it performs its normal attack and briefly flashes the bar, without spending soul power.
• At 100%, it also displays FROSTMOURNE HUNGERS! in red and unleashes a blue frost wave. All 100% soul power is consumed, even if no enemy is executed.
• The wave reaches 20 metres in a 100-degree forward cone. Walls and terrain block its execution checks.
• Each enemy below 40% of its maximum health has a separate 30% chance to be instantly killed. Enemies at or above 40% are unaffected by the execution effect. The normal power attack still deals its usual damage.
• Friendly players are protected unless both players have PvP enabled. Tamed creatures and neutral non-enemies are protected.
• Executed enemies can contribute new soul power after the bar is consumed.

Upgrades and required materials

Every upgrade adds 43 Slash, 24 Frost, and 16 Spirit damage: 20% of the tier-1 damage per level.

Required items:

• Bloodgold
• Flametal ingots (the current ingots, not Ancient Metal)
• Crown Jewels

Use a level-6 Black Forge to upgrade through level 4. Use the Forge of Potential for further improvements beyond level 4. Each improvement adds one level, is guaranteed, and preserves the original sword.

Upgrade	Station	Bloodgold	Flametal	Crown Jewels	Slash / Frost / Spirit
1 → 2	Black Forge level 6	10	20	2	258 / 144 / 96
2 → 3	Black Forge level 6	12	24	3	301 / 168 / 112
3 → 4	Black Forge level 6	15	29	4	344 / 192 / 128
4 → 5	Forge of Potential	18	35	5	387 / 216 / 144
5 → 6	Forge of Potential	22	42	6	430 / 240 / 160

Each upgrade costs 20% more than the previous upgrade, rounded up separately for each material. Forge of Potential improvements continue this progression beyond level 4. No additional battle idol is required.

Installation and updating

Install BepInExPack_Valheim and Jotunn; mod managers install the declared dependencies automatically. Install FrostmourneHungers on the server and every client, all using version 1.2.3.

For manual installation, copy the package's BepInEx folder into the game/profile folder. If updating an older build named Frostmourne.dll, remove that old DLL first. Keep only the new FrostmourneHungers.dll.

Existing swords and pedestals are preserved. Keep BepInEx/config/FrostmourneWorlds alongside your world backups; these journals prevent the pedestal from issuing a replacement sword. Soul power on existing swords starts at 0% until earned.

Swords may travel between worlds. Each world can issue its own sword, so imported swords can coexist with that world's sword. Restoring copied or older character saves can duplicate or roll back items and stored power; the mod cannot prevent save-file duplication. A disconnect during the original pedestal claim can lose delivery because issuance is deliberately never repeated automatically.

Compatibility

Built against the installed Valheim 1.0.16 assemblies, BepInEx 5 and Jotunn 2.30.2. Compilation and automated rule checks pass. HUD appearance, enemy-owner networking, PvP, and other combat/UI mod combinations still require live in-game testing.

Original models and icon; no Blizzard assets are included. This mod is not affiliated with Blizzard or Iron Gate. Source is MIT licensed. Build instructions and technical details are in DEVELOPING.md in the source project.

Admin testing command

While holding or sheathing your own Frostmourne, open the F5 console and enter fm_soul 100 to fill the bar. Use fm_soul 0 to empty it, or any whole number from 0 through 100. The host or an administrator in the server admin list may use it; the server verifies permission. This changes only your existing sword and does not grant another sword. Launch Valheim with -console if F5 is unavailable. A full bar is still required for the frost wave; ordinary secondary attacks below 100% only flash the meter.
