Trebonius's Freezing Grasp

Target up to 4 creatures you can see within range. Targeted creatures must make a constitution saving throw or take 3d10 cold damage, taking half as much on a successful save. On a failed save however, creatures suffer from the following for 1 minute: 

• Disadvantage on attack rolls 
• Halved Movement speed
• 1d6 cold damage

Creatures can repeat this saving throw on their turns, ending the effects on a successful save. Enemies that are reduced to 0 hit points by this spell become frozen statues until they thaw.

For every spell level this spell is cast at above 3rd: Target 1 additional creature.
