Improvised weapons and handidness / weapon specific feats

[Xeth1313]

If you are using an improvised weapon, in the example a Sledge, do feat you have taken that affect Earthbreakers also affect the Sledge? The feat I am curious about is

With this feat would a character be able to wield a Sledge one handed, as they can wield an Earthbreakers? Or is the Sledge not an Earthbreaker as feats would be applied to?

I am inclined to believe they are treated as distinct, but I don know how that works generals and can't find an FAQ explaining the generics. Do feats that work on specific weapons apply to improvised versions of those weapons?

I'd say many actual weapons are more similiar to other actual weapons than to improvised counterparts, so weapon specific feats should be specific.

I mean if you need seperate weapon focus feats for a spear, long spear, and short spear, an improvised pointy stick is none of those.

RAW, no, you cannot use a Sledge with Earthbreaker feats such as Thunder and Fang. But tbh, it doesn't really change anything mechanically, so I would allow it. This is something you should discuss with your GM.
