Chains of Ice

 Frozen metal chains shots up from beneath a target within 60 feet of the caster. The afflicted target must make a Strength saving throw. On a failed saving throw, the target is Restrained and suffers 2D6 Cold damage. Succeeding the saving throw causes the spell to fail.

At Higher Levels. Increase the amount of creatures that will be chained by 1 for each spell slot used above 1st level.
