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.

Nanite

Source Alien Archive pg. 67
Item Level 6
The nanite fusion gives a weapon the nanite burst critical effect. When this critical effect is triggered, a cloud of nanites detaches from the blade and begins devouring the target, swarming over it and dismantling it at the molecular level. In this situation, the weapon deals double damage as normal, but all of the damage is treated as acid damage, and the target must succeed at a Fortitude saving throw (see page 181 of the Starfinder Core Rulebook for how to calculate the DC) or be nauseated for 1 round. When you score a critical hit with a weapon that has multiple critical hit effects, you can apply only one of those critical hit effects of your choice. Only melee weapons can have this fusion.
