Bone Spire

Build towering bone-covered monuments that store Bone Fragments and protect the surrounding area from hostile spawns.

The spires

Capacities assume the standard 50-fragment stack size. Mods that change stack sizes also change capacity and growth thresholds.

Both spires accept only Bone Fragments. Both start empty. Stored bones can be withdrawn, reversing growth and reducing protection.

The Greater fills from its broad base upward, covering a slender Core Wood framework with a mixture of skulls and other bones. Its upper framework remains exposed until enough bones are stored.

The Lesser begins as a bare 4m pole. Long bones accumulate in staggered arrangements, accompanied by fitted lashings. Another 4m pole appears when the covering approaches three-quarters of the current section. Different placed Lessers have consistent variations in their bone arrangements. Both spires use native Core Wood meshes and materials with slimmer proportions.

To open a spire, aim at a side within reach. You can reach higher sections from a platform and turn away while the inventory is open.

Area protection

A Greater Spire's own radius grows linearly from 10m to 100m. Half capacity provides 55m before Lesser bonuses.

Each Lesser within the Greater's fixed 100m horizontal linking range contributes in proportion to the number of Bone Fragments it holds.

Every stored fragment contributes. Each Lesser's bonus is capped at 5m, including when excess items are retained from an earlier version. There is no combined bonus cap. A Lesser can contribute to multiple Greaters within range, but provides no independent protection.

Expanded protection does not extend the linking range. An empty Greater retains its 10m base radius and can receive Lesser bonuses. Depositing or withdrawing bones updates the current protection radius.

Equip the Hammer to see nearby Greaters' protection boundaries projected onto the ground. While placing a spire, an amber ring marks the fixed 100m linking range. Where the boundaries coincide, only the protection ring appears. Hover text displays the current protection and Lesser bonus.

Protection blocks natural hostile spawns and raid attackers whose spawn locations fall inside the radius. Ordinary neutral wildlife and Dvergr are unaffected. Existing enemies can still enter, and raids can still begin or spawn outside the boundary.

Boss summoning, physical creature spawners, console commands, and custom spawning systems from other mods are outside this protection.

Installation

Install Bone Spire through Thunderstore Mod Manager or r2modman, then launch Valheim through the manager. BepInExPack Valheim and Jotunn are required and listed as package dependencies.

Both spires appear in the Hammer's Misc category / Storage tags. Discover Core Wood and build them within reach of a workbench.

Updating

Update through your mod manager and restart Valheim. Existing spires receive the new inventory dimensions automatically.

Stored items are retained. Inventories with more stacks than the new grid can hold temporarily keep extra rows. Withdraw excess stacks to finish resizing. Additional deposits are disabled while those recovery rows are needed. The new capacity determines growth and protection, with excess bones counting as full capacity.

Compatibility

Early-access release for single-player Valheim. Multiplayer compatibility is not verified.

Empty and dismantle placed spires before removing the mod from a world you intend to keep.

Changelog

0.1.9

• Added the Lesser Trophy Spire. Mount any trophy at its native scale. A bound wreath and eight parallel bone bundles grow as the shaft fills.
• Hang Dvergr Lanterns beneath the Greater’s four projecting beams. Attach and recover individual lanterns from ground level.
• Added configurable local nighttime atmosphere around Greater Spires. Natural weather returns outside their range and at dawn.
• The Greater now costs 28 Core Wood. Both Lesser variants cost 3 Core Wood. Increased Lesser shaft lashing thickness by 50%.
• Added configurable protection radii, Lesser contributions, and linking distance. Boars, deer, necks, and hares may spawn naturally in protected areas. Raid attackers remain subject to suppression.
• Simplified spire hover text, switched Hammer thumbnails to bundled images, reduced mesh loading work when changing detail levels, and refreshed saved contents before destruction.

0.1.7

• Both structures now start with a Core Wood frame. The Greater costs 10 Core Wood and the Lesser costs 1.
• The Greater stores 18 stacks in a 6×3 grid. The Lesser stores four stacks in a 2×2 grid. At the standard stack size, they hold 900 and 200 Bone Fragments respectively.
• The inventory prompt and opening action now use the surface you aim at. You can open a spire from a nearby platform and keep it open while turning away.
• Fixed an inventory range conflict with other container mods and a coverage-ring error when placing spires or returning to a world.
• Existing stored items remain available for withdrawal, including stacks beyond the new capacity.

0.1.6

• Increased the Greater Spire to approximately 20m, with bone covering that accumulates from the base upward.
• Preserved the Greater's existing mix of skulls and other bones.
• Restored slender Core Wood proportions throughout both structures.
• Replaced uniform Lesser bone rows with staggered, tightly fitted arrangements and three visual variations.
• Extended Lesser growth to 12m, adding 4m pole sections as the covering rises.
• Reduced Lesser storage to 3 columns by 2 rows, holding 300 standard Bone Fragments.
• Greater base protection now scales from 10m when empty to 100m when full.
• Lesser bonuses now scale with stored bones, reaching 5m at full capacity.
• Increased the fixed Lesser linking distance to 100m and updated coverage markers and hover information.
• Added distinct model-rendered build-menu thumbnails and Thunderstore artwork featuring both spire types.
• Extended inventory recovery to preserve larger legacy layouts through subsequent saves and reloads.

0.1.5

• Replaced custom timber supports with native Core Wood meshes, materials, and detail levels on both spires.
• Lesser inventory is now 4 columns by 3 rows, holding 600 Bone Fragments at the standard stack size.
• Lesser Spires contribute +5m only while full.
• Greater base protection now grows with stored bones, reaching 50m at full capacity.
• Added workbench-style ground coverage markers and a separate 50m linking boundary while building.
• Lesser growth now fills an exposed 4m pole before extending to a second pole, reaching 8m.
• Spaced Lesser bones to keep neighboring shafts and joints separated.
• Unified inventory prompts, opening, and closing distance at the surface of each spire.
• Added reduced-detail bone models for distant viewing while preserving complete growth layers.
• Retained stored items during inventory resizing.

0.1.4

• Fixed an initialization failure that prevented both spires from appearing in the Hammer build menu.
• Resolve building shaders directly from loaded native materials.

0.1.3

• Packaging-only re-release of the 0.1.2 build for Thunderstore. The plugin binary is unchanged and still reports version 0.1.2.

0.1.2

• Greater Spire inventory is now 8 columns by 4 rows; Lesser Spire inventory is 7 columns by 3 rows.
• Growth now follows the capacity of the revised grids, including modified Bone Fragment stack sizes.
• Empty Lesser Spires display a bare wooden post. Bone covering and lashings appear together when bones are deposited.
• Reworked native wood, bone, and lashing material selection and texture assignment.
• Disabled material displacement on the spires to address wavering hammer placement previews.
• Rebuilt model surfaces with closed ends, consistent outward faces, and complete bone volumes.
• Restored the Greater Spire's full bone coverage and corrected growth-layer rendering.
• Preserved existing inventory contents during resizing, with temporary recovery rows for excess stacks.

0.1.1

• Added Greater and Lesser Bone Spires with bone-only storage and reversible visual growth.
• Added 50m Greater Spire protection, extended by 5m per qualifying Lesser Spire.
• Added natural hostile and raid spawn protection.
• Added Thunderstore packaging and mod-manager installation.
