Seems likely to me that they've renamed some of the runes, so Multistrike is now Hydra and, I dunno, Striking is now Viper?
Still wish they'd use some of the names from D2's Runes. Shael (IAS) for Striking/Viper, Gul (%AR) or Jah (ITD) for Multistrike/Hydra? Power could be Ber (CB) or Lo (DS), etc.
