Engineers will discover schematics for many new and intense gadgets
from the inventive minds of the Gnomish (and Goblin) R&D labs –
such as Nigh Invulnerability Belts and yes, Rocket Launchers. You will
be able to use a Mote Extractor to gather resources from clouds of gas
and magic found in various parts of Outland. An important tool being
added for the raiding engineers is the ability to make various colored
smoke flares to mark important locations.
