Bone Welder

Bone Welder: Drag onto a fractured limb in the health panel to cut healing time to a quarter.

Use, trade-offs and mechanics

A bone welding tool accelerates an existing fracture's recovery; it does not instantly restore an entire limb. The community reference multiplies the remaining fracture-healing time by one quarter. The timing matters: the same proportional reduction removes more waiting from a fresh, long fracture than from one that is nearly healed. Apply it directly to the affected limb in the health panel.

Its trade-off is additional tissue damage. One application removes skin and muscle health, adds pain and bleeding, and raises blood viscosity. Inspect those fields alongside the fracture timer instead of judging the result only by shorter bone recovery. The item description recommends keeping dressing available, and the recorded bleeding increase explains why. Existing blood loss changes the immediate priority.

A full-condition tool provides two applications because each costs fifty percent condition. The reference lists both loot and crafting sources. Crafting needs INT 14, scrap panels, wire bundles, a high-condition circuit board, bio-chem fluid and L.R.D. Serum. Those requirements differ substantially from ordinary dressing.

Compare the tool's remaining condition with the specific limb's bone, skin and muscle state. A successful weld can shorten the original injury while adding a new wound that still needs attention. The tool's two-use limit also means a second fractured limb competes for the same item rather than receiving an unlimited follow-up treatment.
