The exact effect seems to depend on the skill. I haven't tested everything, but:
- Walkers work correctly
- Selecting bombers instead makes a talisman for "use only swimmers" (according to Crane)
- Cloners is similar, becoming Stoners
- Miners doesn't work at all. The text file references only using the skill "14" (which of course, there's no skill called "14").
There's two options for a workaround:
a) Edit the NXLV file by hand to correct the talisman
b) Instead of using "Use only skill", set a limit of 0 on all other skills
