Characteristics
Overview
10% chance to produce a free bonus item when crafting in batches. Ineffective when crafting explosive and raid related items.
Everything you craft in bulk gets a little cheaper with it. The game text gives a 10% chance of a free bonus item when crafting in batches, nothing more. Over a wipe of queued arrows, pistol rounds and medical syringes, those freebies save material you farmed by hand.
The exception sits in the same text: explosives and raid-related items do not count. So the group that queues C4 the night before a raid gets nothing out of it, while the player who keeps everyone stocked with ammo and meds gets the most. A solo who crafts a few things at a time will rarely see the bonus at all.
Its row lists three gears and 200 scrap at a Level 1 workbench, but the game files say it cannot be crafted or researched at all, and the same goes for the Accelerated upgrade. So you do not pick between them by cost; you fit whichever one loot hands you. The two answer different problems. Accelerated saves you time on a batch, this one saves you material.
Recycling
At power grid stage 2 a green recycler works at 60% instead of 50%. Yields depend on the recycler.
