Zombies immune to blunt weapons?

[LuckyTom]

When battling the Zombies in the Moathouse, I always see "0 HP" when my chars hit. All have blunt weapons like Maces or Warhammers. Are Zombies immune to blunt weapons?

not immune, exactly. They have damage reduction 5 or 10 I believe with respect to non-slashing weapons. This means that your bludgeoning damage is simply being reduced to 0 or less. I'm not sure, but piercing weapons (such as arrows and bolts) also bypass this reduction.
