I was not able to reproduce this. I made a simple "Terror and Thirst Focused" + Hechaton combo (shoot laser beam, transform what it touches), and no Sentry is spawning in the empty tiles the laser is traveling through. Let me know if you remember what recipe you used.
Tutorialization is what I am working on right now! Hopefully I can explain the game without dumping a ton of text on the player.
I don't remember what combo I used, so it's entirely possible that I did something silly like combining it with Rebuild the Flesh of Old and then forgetting what spells I used. (That said, I think there actually isn't space for that combo on the grid, so I'm confused.) On that topic, I would very much appreciate it if you could see what spell pattern you used when hovering over a spell you've created- it's hard to keep track sometimes.
