Minor Cryoxadone + cryostylane beakers

[Flourish]

Since cryotubes apply the chemicals in the beakers to the person inside the tube, after a little while, they get trapped in ice cubes (due to the cryostylane) that spawn outside the tube. It's a bit odd.

edit: And when you break out of the ice cube, you're technically also still in the cryotube, so you still get continuously healed until it ejects you.
