Swordbow

The limbs of this bow appear to be made of sharpened metal, as if the bow had been crafted from two thin, flexible swords.

This +1 longbow changes into a +1 longsword (or vice versa) when activated. You can interchange bow and sword attacks as part of the same full attack action.

In sword form, the weapon features a bowlike grip and a pommel that resembles the curving tip of a bow. In bow form, the weapon is made of metal, and each limb of the bow resembles a sword blade.

In either form, a swordbow has the same enhancement bonus. A swordbow’s enhancement bonus can be improved as if improving two separate weapons (for example, improving a +1 swordbow to a +2 swordbow costs 12,000 gp, just as if you were improving two +1 weapons to +2). A swordbow can have special weapon properties added to it (such as flaming); such properties cost twice the normal amount (again, as if improving two separate weapons) and apply to both weapons if possible. If a property can’t apply to both weapons (such as vorpal or distance), it applies only to the swordbow when it is in an eligible form (for instance, a +1 swordbow of distance is a distance weapon only in bow form). If a property can apply to the weapon in only one of its forms, it does not cost double the regular price.
