You should've picked it up.
I've only found, other than from HF, an Ist from Hell Countess. Once an Ohm dropped in a game, but I was in a different area.
That is when I love Telekenesis or Whirlwind.
If HR means less than Ist, I have found 3 puls, 1 Um, and an infinite number of Hels. But that is as low as I will go with the designation HR.
