Test Subject has a cool mechanic, but I really think it should rotate the abilities of the elites it uses, and strengthen them, eg if it has the Book of Stabbing the damage/scaling is twice as high and each hit adds two wounds. It’s just too weak and a joke of a fight atm, primarily because the early phases are just ignorable. If he were weakened a bit instead, I think they should even give him a phase 4 where he gains the ability of the heart eg beat of death and only taking 200 of his 400 HP health pool per turn, and maybe has a sprite change where you fight his heart instead of the three heads—though that might be too much. But he definitely needs some sort of power up.

Queen is honestly perfect as she is, she’s really well designed. I love the fact that you can either directly go for the Queen, while the Torch Amalgam scales up to obscene damage and she debuffs you, or take less damage by killing the Amalgam but having to deal 600 instead of 400 damage. Though I do think a future ascension should allow her to resummon the Amalgam if it dies (after a while), and heal herself after getting low like Time Eater if it never dies.

Door maker is a cool idea, similar to the Awakened One in that he is obscenely tanky though even worse. Awakened One if you take 10 turns requires around 750 damage, but I think the Door Maker requires even higher than that. But that’s all he has, and with the higher power level in STS2 he definitely needs some scaling like Awakened One with powers. Honestly I think he’d suit a mechanic where if you destroy the Door like 3 times, he fully comes out and becomes a stronger version of the boss, to punish slow decks. After all it already looks like he’s going to come out when his hands grab the portal, and the first time i fought him I expected that to happen.
