Xaku — First Bones
Star Chart build. Grasp of Lohk steals guns. Vast Untime slows, strips, and freezes your other timers. Learn 2 and 4 before you cycle The Lost. Primed Continuity and Primed Flow are the first real upgrade — not Blind Rage.

Wrong drop or mechanic?
Why this build?
Star Chart for Junctions through the Outer Terminus. Steel Path is the next card, not this one.
Health: Inventory unknown — Mark what you own. Until then this is a recommendation, not a test you failed.
- Xaku is stolen guns plus Untime. The 2026 identity is not Xata's Whisper.
- You are a skeleton with 146 armor. Untime slow and Grasp killing things is the health bar.
- Duration plus Untime pause means Grasp can last a whole Defense wave if you recast 4.
Don’t use this for: Steel Path endurance · level-cap content · Capture / short missions · Exterminate speedruns · solo level-cap
Accessible mods and a working energy / survivability loop
Bring: Your gun is optional — Stolen guns scale with enemy level. A primer still helps. Do not skip Grasp because the guns look small.
Alternative if…
- You wanted the ability loop, not guns → Vast Strip

Pocket card. Stick this on a second screen; the long version is the mission below.
- 1Grasp of Lohk (2) a pack. Guns rip off and orbit you, shooting for you.
- 2Vast Untime (4). Slow, Void vulnerability, armor strip on the blast, and your 1/2/3 timers freeze until 4 ends.
- 3Xata's Whisper (1) if you want Void on your actual gun. Starter can skip it.
- 4The Lost (3) later. Accuse / Gaze / Deny is a cycle — do not panic-tap it.
First mission — press these buttons

Grasp a pack
22. Rifles rip off and float around you, shooting.
You will know it worked when: A halo of guns. Enemies dropping without you firing.

Untime
44. Slow, a Void blast, you look even more skeletal, and the gun timer freezes.
Common mistakes
Shooting instead of stealing
Your starter rifle is worse than their level-scaled guns. Press 2.
