Kingdom Rush Vengeance TD+: Eternal Bones Achievement Guide

To unlock the secret Eternal Bones achievement in Kingdom Rush Vengeance TD+, locate and click every scattered fragment of the bone dragon Bonehart resting in the peripheral terrain of the stage. Once all bone piles are activated, the skeleton reassembles, roars, and flies off the map, immediately granting the achievement.

How to Reassemble Bonehart

Bonehart's remains appear as distinct, clickable bone piles resting around rocky outcroppings and peripheral areas outside the main enemy path. Activating them in sequence brings the skeleton together.

1. Inspect the Terrain: Scan the edges and background props outside the main path for large dragon bones that stand out from ordinary rocks.
2. Select the Skull and Spine: Click or tap the horned skull and the central spinal vertebrae. Each piece shifts position with an audible rattle.
3. Attach the Ribs and Limbs: Click the adjacent rib cage pieces and claw fragments to lock them onto the main torso frame.
4. Unfold the Wings: Click the elongated skeletal wing struts situated near the outer edges. The wing frames expand into flight position once attached.
5. Trigger Reanimation: When the final piece snaps into place, Bonehart fully reanimates, lets out a screech, and takes flight to finish the secret event.

Timing and Interaction Tips

Hunting for small terrain elements during active combat can lead to leaked enemies and missed hero ability timings. Use these practices to complete the puzzle cleanly:

• Solve Before Wave 1: The safest time to reassemble Bonehart is during the initial setup phase. Before calling Wave 1, you can take as much time as needed to inspect the stage without risking track defenses.
• Listen for Audio Confirmation: Each valid bone piece produces a distinct rattling sound effect when clicked. If no sound plays, the tap did not register.
• Adjust Zoom on Mobile: If adjacent tower pads or rally flags interfere with clicking small bone hitboxes, zoom the camera in closer to isolate the fragment.
• Play on Any Difficulty: Achievements register across all settings, including Casual. If an active run becomes too hectic, restart the mission on Casual to click the fragments without defensive pressure.
