Some ERT skills were way too advanced. 
I only got through half of them, will probably do more while this is up

# Explain why it's good for the game

<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding, and may discourage maintainers from reviewing or merging
your PR. This section is not strictly required for (non-controversial)
fix PRs or backend PRs. -->
Average UPP Pvt shouldn't be able to be superman.

# Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. Please note that
maintainers freely reserve the right to remove and add tags should they
deem it appropriate. You can attempt to finagle the system all you want,
but it's best to shoot for clear communication right off the bat. -->
<!-- If you add a name after the ':cl', that name will be used in the
changelog. You must add your CKEY after the CL if your GitHub name
doesn't match. Be sure to properly mark your PRs to prevent unnecessary
GBP loss. Maintainers freely reserve the right to remove and add tags
should they deem it appropriate. -->
