Frost is a modded Subclass of Wizard that focuses on utilizing Cold damage spells

When attacking a creatue that is Frozen or Prone with a Cold spell, you have Advantage and the number you need to roll a Critical Hit is reduced by 5. This effect can stack.

Dealing Cold damage to a creature with a spell grants you 2 turns of Icicles. You can expend 5 turns of Icicles to make your next Cold spell benefit from Shatter regardless of conditions.

Your Cold spells that would normally target only 1 creature can target an additional creature.
