Vigilance is the key-word here.
Death by Jegga, being far pushed off the Vantage Point, sealed in Mines,
maybe even Scattersprayed... They are all nasty but can all be avoided
relatively easily, especially at higher skillranks.
As for the immunity, the first Jegga brew will drop that and Ender will
brew another to get you.
Personally, I use the RESIST command rather than rely on Immunity, and
have a good supply of Denallo to cure myself if need be.
Welcome to the world of the hunted Pacifists.
