unsummon

You find the hidden threads of magic in a magically summoned creature, item or illusion that you can see within range. If the summoned creature, item, or illusion is made of a spell of 2nd level or below, they disappear immediately. If it was a creature or item, it disappears back to its original plane of existence. If the creature or item is not summoned through a spell, this spell fails. If the summoned creature, item or illusion is of 3rd level or higher, you must make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature, illusion or item disappear. If the target is neither an illusion, nor a summoned creature or item, this spell fails automatically.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can choose either to automatically dismiss a magically summoned creature, illusion or item of the corresponding level, or try to target another creature, item or illusion. You cannot however chose both options.
