Yeah, it was 5 over 9 swings, without me stopping my mining; when the vein ran out, about 15-20 seconds after I started mining, I was surrounded by 5 corpses. And, despite not having healing at the time, (was a couple years ago - I added barely enough to rez others last year) when it happened, I only fell to about half hit points. These days, using an elemental slayer blackthorn's kryss, I'd probably not even fall that far in HP.
And, Lilac, I know the pain. My first day in a week or so mining, yesterday, and my usual start place had changed ore types. My first swing brought up a piece of iron ore - and a paragon copper elemental. Before I knew what hit me, I was dead.
