requires attunement, legendary artifact
Wearing this ring gives you access to an infinite magical arsenal. As a bonus action, with a simple statement of its name, you can summon any mundane weapon that you have seen and equip it.
This weapon is considered a +2 magic weapon. It appears as ethereal wisps of magic Any weapon that requires simple ammunition (bolts, arrows) need none. You are considered proficient with the weapon, even if you wouldn't be otherwise.
If you summon another weapon you can choose if the previous weapon immediately disappears into the ring, or becomes mundane and remains in the world for 1 minute before disappearing into mist.
Twice per long rest you can, as a reaction, summon ethereal blades and weapons to spin around you in your defense. Anyone within 10ft of you must make a DC18 dexterity saving throw or receive 10d6+2 slashing damage. Half on success.
