It's directional explosion door charge. It knockbacks and slightly damages critters in a cone of 3 hexes behind the door (one direction) when exploded.
Should be in the active hand / utility, skill 4 on the door.
I suck in English, so correct _functional_ description which will help players to successfully use and predict behaviour of this item would be appreciated.
Same goes for door jammer which is being sold at the same trader and currently look like a crowbar. (skill 8 ). It uses "door holding" mechanics, but doesn't require to stay next to the door. The effect goes off after 5 minutes
Same goes for images for these items (only inventory images)
