Elizabeths Eldritch Maw

Tearing a hole in the fabric of reality you summon forth a wriggling mass of tentacles and teeth, a great maw of some unknown horror from the far realm appears in a place of your choosing within range.  

If a creature goes within 5ft or ends its turn within 5ft of the maw one of its tentacles attempts to grapple that creature. The creature must make a dexterity saving throw or be grappled. At the beginning of your turn the tentacles drag grappled creatures into the center of the maw and they are restrained immediately taking  2d6 Piercing damage. As an action a creature may attempt to break free with a successful strength or dexterity check at disadvantage. If a creature begins its turn within the 20ft area they are automatically restrained

A restrained creature suffered the restrained condition and suffers 2d6 Piercing damage at the start of their turn until they escape.

For every level above 3rd the caster may summon an additional maw. Another vial ink per level higher than 3rd is required for additional maws.
