Wand, rare (requires attunement by a spellcaster)
This wand has 7 charges. While holding it, you can use an action to expend 1 of its charges to cause a thin blue ray to streak from the tip toward a creature you can see within 60 feet of you. The target must succeed on a DC 15 Constitution saving throw or be paralyzed for 1 minute. At the end of each of the target's turns, it can repeat the saving throw, ending the effect on itself on a success.
