Ether Spear

This spear can slip through the Ethereal Plane to reach its destination. You gain a +2 bonus to attack and damage rolls made with this magic weapon, which deals force damage instead of piercing. When you take the Attack action with the spear, you can choose a point you can see within 20 feet of you. The tip of the spear vanishes and reappears at that point, allowing you to make melee attacks with the spear against a creature in or adjacent to that space until the end of your turn. You ignore half cover with these attacks and treat three-quarters cover as if it were half cover.

You can use a bonus action to see 60 feet into the Ethereal Plane for 1 minute. Once this property of the spear has been used, it can’t be used again until the following dawn.
