I have been told by EO that we are expected to use the Weaponmaster level 1 bonus feat on it, as provided by the Ravenloft wiki.
Although I think that the table should be amended to be 0 bonus feats at level 1 in that case, since the feat is effectively mandatory. It was my understanding that such tables represented the extra bonus feats that PotM granted to classes, not the ones they'd naturally receive.
