Concussion Grenades

Overview

Grenade Launcher-only magazine perk. Grenades fired from it emit a blast that Staggers enemies caught in it. Stagger is guaranteed against targets without immunity. The perk applies a -200 blast radius modifier, so the blast is smaller than the base weapon's.

It rolls on about 16 weapons, including Truthteller, Flash and Thunder, Orewing's Maul and Resilient People. Other magazine options on grenade launchers include Mini Frags and Sticky Grenades.

Earlier versions

A 2018 player report on the Bungie forums described a much stronger effect: a blast radius locked at 55, a brief blind effect, aim pulled to a random spot, and the target's current action halted. Those accounts are from 2018 and are not reflected in the current description, which covers stagger and the blast radius modifier only.
