Shock Weapon FusionTweet
(from Starfinder Core Rulebook)
The shock fusion weaves the electrical energy of the universe into the weapon’s form. Half the weapon’s damage type is replaced with electricity damage. You can activate or deactivate the shock fusion as a swift action. If the weapon already deals two types of damage, replace one of them with electricity (you decide which damage type to replace each time you activate the shock fusion). You can add this fusion only to a weapon that does not already deal electricity damage. This fusion never causes a weapon that normally target KAC to target EAC.
