Dervish Dance Feat, the scimitar and the Magus

[Morien]

I apologize if this has been asked before. I just can't find it.

According to the posts, the DEX build Magus is one of the better builds. It depends on Weapon Finesse, Dervish Dance feats to be combined with the Scimitar.

I am confused as Weapon Finesses specifically states, "Light" weapons. Scimitar is NOT a light weapon according to Core rulebook. Has this been changed by errata anywhere?

Thanks in advance.

Indeed, Weapon Finesse doesn't apply to scimitars. Dervish Dance, however, does.

When wielding a scimitar with one hand, you can use your Dexterity modifier instead of your Strength modifier on melee attack and damage rolls. You treat the scimitar as a one-handed piercing weapon for all feats and class abilities that require such a weapon (such as a duelist’s precise strike ability). The scimitar must be for a creature of your size. You cannot use this feat if you are carrying a weapon or shield in your off hand.

I believe Dervish Dance Feat can be found in the Inner Sea World Guide.

The DEX vs STR Magus is a matter of opinion. The DEX isn't as MAD as the STR version is why most people like it better.
