Buy OSRS Mystic boots
Mystic boots are magic footwear in Old School RuneScape. They are part of the Mystic robes set and go in the feet slot. To wear them, you need 40 Magic and 20 Defence.
These boots give a +3 magic attack bonus and a +3 magic defence bonus. The magic attack bonus is why mages like them. It helps your spells hit more often, so they fit well in offensive magic setups. Silly jester boots have a higher magic defence bonus, but they have no magic attack bonus, so mystic boots are still usually the better pick overall.
Mystic boots are light at only 0.453 kg, so they will not slow you down. They are tradeable and noteable. You can also store them in a magic wardrobe in your player-owned house along with the rest of your mystic set.
The blue version can be bought from the Wizards' Guild in Yanille. You can combine mystic boots with a Shattered relics mystic ornament kit to make Mystic boots (or) for a new look. These boots are a solid choice for any mid-level mage who wants stronger magic attacks.
