Malediction Weapon Fusion
(from Starfinder Armory)
Once per day when you successfully attack a foe with a weapon with the malediction fusion, as a reaction you can cast bestow curse on the target as a spell-like ability (using the weapon’s item level as the caster level). This does not provoke an attack of opportunity. If the weapon with this fusion has an item level of 14 or higher you may use this ability twice per day, and if it has an item level of 19 or higher you may use this ability three times per day. A weapon cannot have the malediction fusion if it also has either the holy or merciful weapon fusions.
