Mist Sabre

The Mist Sabre is a Light Blade-class Artifact weapon found in.

In
The Mist Saber is found in a treasure chest in the exterior portion of Aqua Rock. As a Light Blade, it can be equipped by Isaac, Felix, Garet, Jenna, Ivan, and Piers.

Its Unleash effect is Searing Fog, which is effectively a standard physical attack that adds 36 damage points and then modifies the resulting damage based on the user's Mercury power and the target's Mercury resistance. The attack may also inflict Delusion on the target. Searing Fog visually resembles the user attacking the target and a blue-tinted white cloud of smoke being emitted on impact.

The Mist Sabre is sure to be a big attack rating improvement on at least one of your Adepts, considering that among the weapons they could be holding are the Comet Mace, Hagbone Mace, Captain's Axe, and various other weapons. It certainly obsoletes any weapon that could be purchased in the shops across the Great Eastern Sea, and is a particularly sensible weapon for the Mercury Adept Piers. Delusion is not a really helpful side effect, though, and other weapons that will replace it further down the line even before Lemuria is reached are the Cloud Brand, Lightning Sword, Glower Staff, and Demon Mace.
