Bellows of Strangulation

This bellows has 6 charges. While you are holding it, you can take a Magic action and use one of three command words to cause one of the following effects:
First Command Word. You expend 1 charge to cause the bellows to suck the energy from one creature you can see within 60 feet. The creature must succeed on a DC 15 Constitution saving throw or have the Incapacitated condition for 1 minute. The creature repeats the save at the end of each of its turns, ending the effect on itself on a success.
Second Command Word. You expend 3 charges to cause the bellows to suck the energy from creatures in a 30-foot Cone. Each creature in that area must succeed on a DC 15 Constitution saving throw or have the Incapacitated condition for 1 minute. An affected creature repeats the save at the end of each of its turns, ending the effect on itself on a success.
Third Command Word. You expend 5 charges to cast the Cloudkill spell (spell DC 17) from the bellows.
