Was dwarf barbarian (crowned with lightening immunity and grod) exploring the sinister cave (along with my GEE companion from DH2). Was able to one-shot literally everything I came across. I heard the step of the royal guard, found the gold and dug to him, and picked up a stack of gold (he used to not turn hostile unless you talked to him after picking it up.
He walked over to me and killed me without a chance for me to do anything. Guess this is what I get for trying to stay unspoiled for the newer releases XD.
