From D&D Wiki
|arcane focus or eye of squid
Up to 100 feet away, an area with sides of 10ft, floating 5ft above the ground will become a portal to an unknown location that can not be entered, and 4 Medium tentacles will come through the portal. Any creature other than yourself or creatures you specify that ends their turn within 5 feet of a tentacle must make a Dexterity save (DC 15) or take 2d10 bludgeoning damage, be grappled by the tentacle, and make a Constitution save (DC 12) or be diseased. Each creature that begins their turn grappled but not diseased must repeat the Constitution saving throw or be diseased. Creatures who end their turn diseased by this spell but not grappled by it may repeat the Constitution saving throw, taking 2d8 poison damage on a failed save. The condition ends when the save is a success.
At Higher Levels. When you cast this spell using a spell slot of 9 or higher, the tentacles are Large and the save DC for disease is 20.
