what kind of scripted effects?
scripts on gear can be done, but with limited use. you can also try using magic effects via enchantment/perk etc
Well I want when the character equips a particular weapon, they equip another piece of armor at the same time. Once they unequip the weapon they just equipped, they equip a different piece of armor at the same time.
For example, if they're wearing a cape, and they go into battle, they'll pull out their sword and shield, and unequip their cape. When the battle is over, they'll reequip the cape, and unequip the weapon they were just using.
