Chrysididae - Yellowjacket

Slim and long, the yellowjacket chrysididae is girded in sickly, yellow and black armor plates that are a fair imitation of chitin. Unlike its kin, the yellowjacket’s chassis is spindly in the middle and bulbous at both ends. Its swelled thorax thrums with voltaic menace, the black plates there popping open whenever an antimagic anchor is launched in a thread of lightning. A quarter of thin, mustard wings hinge to its shoulders and fold tight when the construct is land bound. Its internal workings are obscured, unlike other chrysididae, but it still moves with silent ease. The last difference between it and other Vespidae miscreations, is that the yellowjacket bears two asymmetrical-crystal eyes; blue and green.

Step 6 - New Solutions. “It turns out that the greater slaad are beyond my means to control. Oh, I can tend them in my charnel garden, but I have had to cull each and everyone. Their chaotic nature and superior intelligence makes them too dangerous to all life on the material plane. That includes you and I, my darling. I have found a solution, however, combining two lesser crystals in a complicated matrix. The yellowjakcet’s unique construction came with an unexpected, but pleasing, side effect. Its anarchic energies naturally disrupt magic by tearing apart its orderly nature. At least, the sort of magic the Planar Guild employs. I am not sure how effective the yellowjacket would be against wild mages, for example. However, I am sure its stinger would slay one of those mad arcanists all the same.” -The Vespidae

Antimagic Anchor (Recharge 6).
