Sunken Spoils

Turn fishing into a dangerous treasure hunt.

Sunken Spoils expands Valheim's fishing system with recoverable treasure, biome-based loot, and an Ocean Disturbance system that makes prolonged ocean fishing increasingly rewarding — and increasingly dangerous.

Features

• Fish up Driftwood Crates, Waterlogged Barrels, and Sunken Chests
• Biome-specific treasure loot tables
• Progression-gated ore and scrap rewards
• Treasure uses Valheim's normal fishing/reeling mechanics
• Configurable treasure fight strength by tier
• Direct inventory rewards, with overflow dropped near the player
• Personal Ocean Disturbance system
• Disturbance-based treasure tier scaling
• Sea Serpent attraction at higher Ocean Disturbance
• Per-player serpent attraction chances and caps
• Severe and Catastrophic disturbance can drive shared Ocean weather
• BepInEx configuration support

Ocean Disturbance

Repeated fishing activity in the Ocean angers the sea.

Disturbance stages:

• Calm
• Restless
• Dangerous
• Severe
• Catastrophic

Ocean fishing can add disturbance from valid bites, hooking treasure, recovering treasure, and slaying Sea Serpents.

At higher stages, treasure tier odds improve and Sea Serpents may be attracted on eligible Ocean bites.

Treasure Tiers

Driftwood Crate

Common treasure with lighter rewards.

Waterlogged Barrel

Mid-tier treasure with stronger rewards and a harder fight.

Sunken Chest

Rare treasure with the highest reward potential and the strongest fight.

Biome Loot

Treasure loot changes based on the biome where the fishing bobber is located.

Supported biome tables include Meadows, Black Forest, Swamp, Mountain, Plains, Mistlands, Ashlands, and Ocean.

Unknown or modded biomes fall back to the Ocean loot table without automatically receiving Ocean disturbance behavior.

Progression

Advanced ore and scrap rewards can be gated behind Valheim boss progression.

Ore rewards can also be disabled or adjusted through the BepInEx configuration.

Multiplayer

Sunken Spoils uses a personal risk/reward model:

• Each player builds their own Ocean Disturbance
• Treasure reward scaling is personal
• Serpent attraction chances and personal caps are personal
• Severe/Catastrophic Ocean weather is shared through the world state

Physical Sea Serpents are normal world creatures and can be seen and fought by other players.
