Cruel Frost

You touch a creature within your reach and draw out all their heat, instilling a deathly frost within them.

Make a melee spell attack, on a hit the creature takes 5d10 cold damage and has disadvantage on attack rolls and Dexterity saving throws until the end of your next turn. Creatures immune to cold damage are unaffected by this spell.

At Higher levels. Casting this spell at higher levels increases its damage by 1d10 for each spell slot above 4th.
