Add specific buff to specific weapon

[Balot]

Is there any way to add a specific buff to the weapon that is equiped by a character, so that it stays in the weapon even if the weapon is unequipped? For example, let's say that I have a Poison Vial and use in a character to add Poison Attack to the weapon, but if I unequip the weapon, the buff will disappear until I reequip the weapon.

Thank you in advance. Sorry for possible english issues.

You may make two weapons: one with poison effect and the other without poison. After player use Poison Vial, you change player's equipment.
However, this results in much more work if there are more vials.

You can use Yanfly's item core and item enhancement plugins if it works for you.
