Nightingale is an artifact weapon that appears in SlashTHEM. It is chaotic-aligned, and its base item is a katana.


Nightingale is the guaranteed first sacrifice gift for Ninjas.


Nightingale deals +3 damage against all monsters, with a 110 chance of dealing an extra 1d5 * 6 damage every attack. While the average damage of +6d5 vs +1d5 * 6 is the same (18), the damage output distribution is conceptually different as you will only get values of 6, 12, 18, 24, and 30.

When invoked, Nightingale toggles invisibility.


Although Nightingale's potential for damage is high, the 110 chance makes its output "spiky" and somewhat unreliable. With that in mind, the average damage is still on par with that of other artifact weapons like Excalibur, and the additional to-hit bonus and invisibility toggle can make Nightingale quite the powerful early- or mid-game weapon.
