Hang onto your heads!

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

When you kill with a Sniper Rifle, Blood Shot activates, and it also activates with a 33% chance on crits, a sniper-focused class MOD. Can continuously trigger Blood Shot in a sniper-centric Vex build. Unique +45% Sniper Damage makes each hit exceptional.

🧩 Origin of the red text “Hang onto your heads!” is a wordplay sniper headshot = enemy “loses their head” shown in black humor (also matches effect = sniper kill on Lootlemon etc.). The primary source confirming it as a quote from a specific work is unverified (the external original source is (unverified))
