Antilife Shell Trap

[Bugb34r]

Specifically the one from Part 5 of The Mummy's Mask...what happens if an Antilife Shell comes into being with a creature inside it? Is the creature shunted out in some direction, or is the shell collapsed because it is being forced against a creature, or is there simply no effect?

[Vatras]

The spell prevents the entrance of living creatures, it does not shunt them out. It does not collapse either, you are both inside it.

If you move away from the creature, that was inside, it would hedge it out as normal. Same, if the creature moves out of it by itself. It will now also collapse, if you force it against it.
