Many years ago, our group played a module that was, I believe, either 3e or 3.5e Dungeons & Dragons that contained a warhammer. Whenever this warhammer was in the presence of drow, the wielder would hear thundering drums and feel the urge to attack the drow. I had thought that it was Whelm from the Return to White Plume Mountain module, but I can't find any stats on Whelm that included this feature.
Was there another such weapon that anyone can find? Or was it perhaps a custom weapon or addition to Whelm that my DM came up with?
