Twin Vipers

You create two vipers at a point of your choice which attack the two closest creatures, up to a range of 30ft. These creatures must succeed on a Strength saving throw or be grappled and restrained by the vipers.

A creature grappled by a viper takes 2d6 bludgeoning damage and 2d6 poison damage at the start of its turn. At the end of its turn, it can remake the saving throw to escape the grapple. On a successful save, the creature is free, and the viper disappears.

At Higher Level. When you cast this spell using a spell slot of 4th level or higher, you can create an additional viper for each slot above 3rd.
