Weapon Fusions

A weapon fusion is a small, prepackaged add-on that can be attached to any weapon to infuse it with magic. Adventurers use weapon fusions to customize their weapons for a specific enemy or to increase a weapon’s overall effectiveness. Weapon fusions are magic unless stated otherwise. While this causes the weapons they are installed in to be considered hybrid items, in truth the weapon and the fusion still operate separately. An ability that affects a magic item could affect the fusion installed in a weapon, but that would not prevent the weapon’s core function from operating normally unless the weapon was also independently a magic device. The hybridized fusion (see page 194) is an exception to this rule, as noted in its description. Weapons with fusions are considered magic for the purpose of overcoming damage reduction.

Interposing

Source Pact Worlds pg. 194
Item Level 5
You can add the interposing fusion only to a melee weapon. Developed and popularized by the Knights of Golarion, this fusion generally adds shining sword icons to the weapon. Whenever you hit an enemy with an interposing weapon, you and all adjacent allies gain a +1 enhancement bonus to AC against that enemy’s melee attacks until the beginning of your next turn.
