Void

A Void appears and one small or two tiny creatures and they must make a dexterity saving throw or be sucked into the void and is considered restrained and is trapped until the void is opened or it succeeds on a dexterity saving throw. This can only be used on one creature at a time until the spell is released or the creature escapes.
At higher levels:
For each spell slot above third you may choose to have it effect 1 more creature to a max of 3. Alternatively you may have it effect a creature of huge size at level six. After a fourth level spell slot is used you can constrict the void and deal 1d8 force damage up to 3d8.
