One of my players wanted to be stealthy and make smoke bombs. Here's what I whipped up on the spot. Give me any feedback on balancing it.

Smoke Bomb
Encumbrance 1
Price 50
Rarity 3
Concealment 1

Seems pretty tame, should be fine. Not sure about price, I suppose that's relative and not really a concern.

There is a smokebomb vial page 103 in realms of terrinoth

Skipping the fluff the Rules part says

As a maneuver, a character can throw a smokebomb vial at a
point within short range. Upon impact, the vial shatters to cre-
ate a thick smoke screen large enough to conceal a single char-
acter and other characters engaged with the target. The smoke
screen provides concealment worth +2 dice (see the Conceal-
ment section on page 110 of the Genesys Core Rulebook).

IT is encum 0 price 25 rarety 4

I'd say:

Concealment +2 or +3 for anyone engaged with the target (a small area) and rarity 4, enc. 1, price 50.
