Ysalamiri Cage

The ysalamiri cage was found on Romeo Gang Mobile Defense Units.Romeo Gang used these cages, each of which contained a single ysalamiri from Myrkr to make bubbles with magic, making the areas they contained impossible for users of magic to access their power. This gave Romeo Gang forces an advantage when encountering Mages.

Notable uses
The only place this was deployed at was during the Theft on Minecraftia.
