Bane of the Sisters

A longbow once wielded by a powerful eldrich archer. It is said that this bow was created alongside the Blade of Reflecting Failure in an attempt to defy the work of the sisters of faith, for its true nature is to defy destiny. When attuned to Bane of the Sisters, whenever you make a ranged attack, instead of firing a single arrow you may instead fire three. When you do so, you draw your bow like normal, focussing your magical energy into the bow two create two spectral arrows. Using the bow, you may hit up to three creatures with your attack. You must make an attack roll for each of the arrows individually, however, they share the same damage roll and additional effects. Additionally, the arrows deal an amount of extra damage equal to your Intelligence modifier. The arrows, however, appear to repulse each other, making aiming difficult, as a result, you roll with disadvantage when attacking with the bow in this way. Additionally, when attempting to hit the same target with multiple arrows a penalty on the attack roll will be applied. This penalty is equal to 2 if shooting 2 arrows at the same target and 3 when shooting 3 arrows. Whenever you manage to hit all three of your shots, the arrows become more aligned for a short period of time. The next triple shot you make with the bow within 24 hours does not have disadvantage or a hit penalty due to the effects of this bow. Those who are closely attuned to the bow will also learn that it has the ability to erase a creature from reality. When hitting the same target with each of the three arrows and each arrow deals damage equal to or above the creature's maximum hp, the creature will die three times, becoming unrevivable by any spell and forgotten by anyone that knew it. Any reference to the creature will also be removed from any sort of record that is not protected by a barier or warding spell of at least 5th level or higher.
