This stone cold blue maul is almost uncomfortable to touch. It provides a +3 to hit and damage rolls. Once the weapon is attuned the wielder gains resistance to cold damage, but also becomes vulnerable to fire damage. On a hit it does an additional 1d12 cold damage. You may expend any unused hit die to channel your inner energy to increase this bonus cold damage by the value of the speng hit die.
Proficiency with a Maul allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Topple. If you hit a creature with this weapon, you can force the creature to make a Constitution saving throw (DC 8 plus the ability modifier used to make the attack roll and your Proficiency Bonus). On a failed save, the creature has the Prone condition.
