Warp Stalkers used to have a spell called Warp which is very similar to what Blink Strikes is today, only they had it many years earlier. You won’t see many hunters using these pets since they don’t provide a buff, but they do have their Time Warp ability. I’ll admit to hardly using mine for that reason, but I still think it’s a cool pet to run around with from time to time.
There are only two beasts with this black warp stalker skin — Gezzarak the Huntress and Zormus. Gezzarak is summoned in Terrokar Forest and Zormus is one of the new rares added in patch 5.2.
