IDK if I missed this in the game as I'm only 16 hours or so in. Maybe this exists in the game or maybe someone has brought this up before, apologies!
As the title says, this could give the stealth mechanic an improvement. Not being reliant on forcing enemies to get killed via mines and thus giving you an opportunity for a non-lethal approach nor would you be required to say, bait enemies with grenades. Maybe this could be used while in stealth. Therefore with this, you don't have to waste grenades or anything else (not like they're not in abundance, there's a risk of collateral with the item, however).
For a game that's set underground with a near-infinite amount of rocks, throwable pebbles sure are missing. Otherwise, a tool that makes a clicking noise would be nice. While the sound stems from your own character, investing in interloper would be good as it allows you to quickly maneuver away.
