Sword of Vengeance

Attunement, +2
Cursed. Whenever you take damage in combat,
DC 15 Wisdom saving throw. On a failed save,
you must attack the creature that damaged you
until you or it drops to 0 hp (or if you cannot
reach it to make a melee attack).

Removing the curse removes the attunement require-
ment and the sword becomes a +2 weapon with no
other properties.
