The miniaturized particle accelerator in the axehead hums with a dim orange glow.
Matter Smasher. You have a +1 bonus to attack and damage rolls you make with this weapon, and you score a critical hit on a roll of 19 or 20 with it. Its damage is considered magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
Nuclear Light. The weapon's head emits a dim orange light out to 10 feet.
Fission Wave. As an action, you can make a single straight slice in the air, cutting any non-living, non-magical material within 15 feet of you in a 90-degree arc. This slice instantly cuts through any organic material such as flesh, wood, or sponge and any soft inorganic material such as foam or nylon, provided they are not being worn or carried. The slice also creates a 3-foot deep incision in hard materials like glass or stone, a 1-foot deep incision in strong materials like metal, or a 3-inch deep incision in specially sturdy materials like adamantine, epikor, or starcore metals. Creatures in the path of this cut must also make a DC 15 Dexterity saving throw, taking 3d6 necrotic damage on a failed save or half as much on a success. You can use this property three times, and regain expended uses at dawn.
