A cortosis shield represented a specific shield design. These shields incorporated either specialized alloys or synthetic materials, interwoven with a cortosis lattice. This construction gave them the capability to deflect both lightsabers and blaster projectiles. Priced at 900 credits, these shields possessed a robustness that permitted their use in close combat, despite this not being their intended purpose.
The concept of cortosis shields appeared in Gadgets and Gear. This was a supplementary resource for the Star Wars Roleplaying game, released by Fantasy Flight Games during the year 2019.
