Thermal vision (which Maggie's goggles also have) decreases the Visibility penalty from non-thermal smoke by one level. I'm not sure what level of smoke a single grenade creates, though. In combination with poor lighting, it can be very effective.<br/><br/>Maggie has Demolitions 1, but grenades are much safer than actual loose explosives. We can just duct tape one to a wall and use the Change Wireless Device Mode action to detonate it. (There is also the option to use Demolitions + Logic to set a grenade up with a physical trip wire.)
