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.

Burst

Source Starfinder Core Rulebook pg. 193
Item Level 2
With the burst fusion, a weapon’s energy damage can form a small explosion that spills onto a second target. The weapon gains the arc critical hit effect (see page 182). If the weapon already has a critical hit effect, when you score a critical hit, you can apply either the weapon’s normal critical hit effect or the arc effect. The amount of damage dealt to the secondary target is equal to one-third the level of the weapon with the burst fusion (minimum 1). Only weapons that deal acid, cold, electricity, fire, or sonic damage can benefit from a burst fusion. If your weapon deals more than one type of energy damage, you select one of those types for the arc critical hit effect to apply to secondary targets when the fusion is added.
