Hello!
There's tons of support in Skript for armor! You can use events like "on armor change event" and "on player change armor" to detect when the armor is changed, if you want to apply potion effects or set variable states. Skript also has full support for attributes (and with SkBee, NBT) with the give and set effects. You can make some pretty nifty armor with custom names, lore, enchants, attributes, and NBT tags with these.
