You gain a +3 bonus to attack and damage rolls made with this magic weapon. In addition, the weapon ignores resistance to piercing damage.

When you attack a creature that has at least one heart with this weapon and roll a 20 on the attack roll, you destroy one of the creature's hearts. The creature dies if it can't survive without the lost heart. The weapon's blade extends and bends to reach the heart of your target. A creature is immune to this effect if it is immune to piercing damage, doesn't have or need a heart, has legendary actions, or the DM decides that the creature is too big for its heart to be destroyed by this weapon. Such a creature instead takes an extra 6d8 piercing damage from the hit.

This feature does not apply when you throw the weapon or use it as a projectile.

A yklwa (pronounced YICK-ul-wah) is a simple melee weapon that is the traditional weapon of Chultan warriors. A yklwa consists of a 3-foot wooden shaft with a steel or stone blade up to 18 inches long. It costs 1 gp, and it deals 1d8 piercing damage on a hit. Although it has the thrown weapon property, the yklwa is not well balanced for throwing (range 10/30 ft.).
