Workbench Upgrades
Every workbench, the Engineering Workbench included, has 10 upgrade slots. Each upgrade fits once per workbench, so all 10 can be installed together.
Accelerated Workbench Upgrade
Crafting a batch gets faster with every item already made in it: 25% less time per finished item, down to 25% of the normal time. Single crafts are not affected.
Comfort Workbench Upgrade
Players near the workbench get at least 100% comfort.
Defensive Workbench Upgrade
Armour crafted at the workbench gets 1 more armour insert slot, up to the item's maximum.
Efficiency Workbench Upgrade
When crafting more than one, each finished item has a 10% chance of a free extra one.
Prototype Workbench Upgrade
Unlocks any tech tree blueprint without the nodes before it, for 2x the scrap. Each such unlock has a 25% chance to fail and use the scrap anyway.
Range Workbench Upgrade
The area in which the workbench counts as nearby is 2x as large.
Recycle Bin Workbench Upgrade
Each craft refunds a random share of up to 10% of every ingredient into the upgrade's own storage.
Reinforced Workbench Upgrade
The workbench gets more health (500 on Workbench Level 1, 500 on Level 2, 750 on Level 3, 500 on the Engineering Workbench) and takes 20% less explosive damage.
Salvage Workbench Upgrade
Tech tree unlocks cost 20% less scrap.
Surplus Workbench Upgrade
Crafts can give a surplus item where the recipe lists one. No current recipe lists a surplus item.
