Wound is a greataxe the color of dried blood. The metal of this axe somehow gives the feeling of death when you touch it. Though it does not feel evil, only a sense of defined purpose to this weapon. The weapon was not designed to be a weapon of malice and murder. It is a weapon that is simply meant to kill when it hits, no emotions involved. A weapon of simple and brutal efficiency. Wound has a growing enchantment which gains its strength from its user's abilty. When your Proficiency Bonus grows from a +2, +4. to a +6 Wound gains a +1, +2, or +3 bonus to attack and damage rolls respectively to each level of the Proficiency Bonus listed. At each bonus to attack and damge rolls there is an additional feature. All features and abilities granted by Wound require attunement to Wound in order to function, otherwise Wound is an ordinary greataxe. Wound's rarity changes based on what abilities are active, meaning the players level that holds it. At the +1 bonus it is rare, at +2 it is very rare, and at +3 it is legendary. 

At +1: Wound gains the wounding ability of a Sword of Wounding. Hit points lost to this weapon's damage can be regained only through a short or long rest, rather than by regeneration, magic, or any other means. Once per turn, when you hit a creature with an attack using this magic weapon, you can wound the target. At the start of each of the wounded creature's turns, it takes 1d4 necrotic damage for each time you've wounded it, and it can then make a DC 15 Constitution saving throw, ending the effect of all such wounds on itself on a success. Alternatively, the wounded creature, or a creature within 5 feet of it, can use an action to make a DC 15 Wisdom (Medicine) check, ending the effect of such wounds on it on a success.

At +2: Wound gains 1 charge. This charge can be used to use Slaughter. Slaughter can be used when you hit a creature with a melee attack with Wound, though it must be used before you roll for damage for the attack. When Slaughter is used double the damage dice that this weapon would normally roll on this attack. This weapons damage dice are consider the damage die that this wepaon deals. A barabarians brutal critical or a paladins smite would not be doubled. This ability when used on a normal attack allows you to roll 2d12 instead of 1d12, and when Slaughter is used on a critical this weapon does 4d12 instead of the normal 2d12 slashing damage. This charge is replenished during a long rest. It can also be recharged after you score a critical hit or kill a creature. The wounding damage die also improves, going to 2d4 instead of 1d4.

At +3: Wound gains an additional Slaughter charge, bringing the total to 2. When you use Slaughter you now instead triple the damage dealt. Wound also now crits on a 19 or 20. The wounding damage die also improves to 3d4

Proficiency with a greataxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
