Kudos to SP, they are at least making some game-changing monsters now (and no, I don't mean Nemeses).
In Eldritch Abomination Maze, we had Faugnar, Jasastur, and Krugbo, all of which are amazing, and now in the Artefact island, we have Tankerion and Flamerion!
In October/November, we can expect to see all of these legendaries on sale (maybe for Halloween, that would fit the theme very well!), and I will buying all of them!
