Powder is the one part of this craft worth planning, and it divides cleanly. A blue shell takes exactly three crafts of gun powder, so nothing is left on the bench whether you make one boomer or a full stack. Behind those crafts sit the sulfur and a pile of charcoal, so throw wood into the furnace beside the ore.
The boomer itself needs no bench, but the powder does: a Level 1 workbench. Queue the powder at base, carry it out and craft the shells wherever the show will be.
Only players who own the item see this recipe; there is no blueprint to research. If powder is short this week, a roman candle lights the sky without any.
