All of the Doomsday Krok Hoard Pack Scarab pets seem to have two new talents in their pool: - Adventure - Elemental Retriever - Combat - Smoke Screen Trained
The reagents to unlock them seem to also drop from the gantlet itself: Smoke Screen Tokens - Krokhotep Elemental Retriever - Time Butterfly & Krokhotep
The pets themselves can drop from the same bosses, so you don't necessarily need to spend crowns to get them. On the other hand, the mounts from the same pack drop from the secret bosses - the Cybermanders. I was able to obtain one of the mounts while running the lowest tier of the dungeon on my max level.
Happy farming!
