You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. While attuned to it, your Hit Point maximum increases by 1 for each level you have attained.
Curse. Becoming attuned to this weapon curses you. While cursed, you are unwilling to part with the weapon, keep it within reach at all times, and have Disadvantage on attack rolls with weapons other than this one.
Whenever another creature damages you while the weapon is in your possession, you must succeed on a DC 15 Wisdom saving throw or go berserk. The berserk state ends when you start your turn with no creatures within 60 feet that you can see or hear.
While berserk, you regard the nearest creature you can see or hear as your enemy. If there are multiple possible creatures, choose one at random. On each turn you must move as close to the creature as possible and take the Attack action targeting it. If you can’t get close enough to attack with the weapon, your turn ends after using all available movement. If the creature dies or can no longer be seen or heard, the next nearest creature becomes your target.
