ADD "ATTACK STATE" TO SKILLS WITH ITEMS

I would like to use an item that adds an "Attack State" to certain Skills.

Ex) Using an item to add a "Poisoned Weapons" state that adds a chance to cause a "Poison" effect on an enemy. The "Attack State" modifier only applies to the normal/default attack. I would like this to also apply to skills that deal physical damage, but not spells or buffs.

Any ideas?
