Also very excited indeed about this.

About poison immunity: I haven't double checked, but I don't think there's any reason to think it doesn't work. Check the manual about how poison damage works. Essentially poison weapons apply a certain amount of "poison damage", 10% of which (rounded up) gets converted to real damage each round. So, lets say 10 poison damage is applied to two units: Unit A has no poison immunity, Unit B has 50% immunity. Both of them will start taking 1 damage per round, but Unit B will only take it for 5 rounds (total of 5 damage), whereas Unit A will take it for the full 10 rounds (total of 10 damage).

Hope that makes sense. So you can usefully give them poison immunity.
