The Ultrasafe Bullet Machine and Saronite Arrow Maker schematics have been simplified to create a full stack of the appropriate ammunition. No longer requires an anvil. Reduced the materials required to make this ammunition.
My read on this is that less materials are required and it produces 5x the amount of ammo. So say instead of 25g in mats for a machine, it's only 20g in mats. Then it produces 5x the amount, so it's really 5g? It sounds like these will be cheaper to use than filling up stacks of rep vendor Timeless Shells. That would really help reduce one of the consumable costs of raiding. Ahh, but I'm probably misinterpreting it.
