Chillsby's Wonderous Workbench

A large workbench appears in front of you, filled to the brim with drawers and slots. It can be as small as an 5 ft cube, or as large as a 20ft cube, and takes the shape of a workstation to accommodate for up to four different types of artisan's tools which you specify at the end of the spell's casting, provided you use those tools to cast this spell. One creature can occupy 5 ft of this workbench to work at it. A creature proficient with the appropriate artisan's tools at this bench can complete progress on magical item crafting at double the regular rate of time and at half the gold cost.
