Javelin of Freedom

Weapon (javelin), very rare (requires attunement)

You gain a +1 bonus to attack and damage rolls with this weapon. While you carry it, you are unaffected by difficult terrain, and spells and other magical effects can neither reduce your speed nor cause you to be paralyzed or restrained. You can also spend 5 feet of movement to automatically escape from nonmagical restrains, such as manacles or a creature that has you grappled. Being underwater imposes no penalties on your movement or attacks.
