The breathing from Radioactive by Imagine Dragons replaces the noises heard when your consumable is used and recharged. Affects kingpin, stoic, tag team, hacker, leech a.k.a any perk deck that overrides your throwable. Not all consumable equipment will use both sounds for some reason (stoic only uses the recharging noise), but both work for leech- that's a topical perk deck right now, right?
