@EVHaste It's all done through Hearthpyre's xyloschemer, yeah. Spawners and traders past the Zapjaws are all gated behind upgrade chips the monsters drop.

@ASH Wish for "Kai Arena Simulator" or check the wish menu.

Infinite tower defense? I'm excited to try this out. I'm assuming these tools are accessed through the Hearthpyre menu, or that there's a quest in-game to explain how to use it?

How do you access the contents of the mod? And what is the wish to test out the sample arena?
