Artificer’s Lab, Portable
Source Advanced Race Guide
The portable artificer’s lab contains everything needed to create magic items, though many of the tools and implements are of only the most basic type. This lab allows the artificer to spend 4 hours crafting each night while out adventuring, and net 3 hours’ worth of work (instead of 2). However, because the tools are all designed to fulfill multiple functions and the portable lab lacks the space and quiet that provide ideal circumstances for creating magic items, the skill check to complete a magic item that had any of its work done using a portable lab takes a 5 penalty.
