Muramasa

Muramasa is a weapon from the Legacy of the Moonspell DLC of Vampire Survivors. It is the evolution of Night Sword, requiring Stone Mask at max level.
==Effects==
Muramasa creates a series of slashes at the closest enemies. When retaliating, it slashes six times around the character and can retaliate every 0.6 seconds.
Muramasa's base damage is doubled and has a lower Cooldown and Interval, compared to Night Sword. The Amount of slashes for each attack is lowered.
Muramasa's base damage is increased by (~1.5 x Greed).
Muramasa has a 10% chance to generate little hearts that heal 1 point of health upon killing an enemy which is 10 times more than its base form. This chance is affected by Luck.
It also gains a finisher, causing every fifth slash to become vertical, covering a large area.
By default, it is capable of dealing critical hits, which deal 2x damage and have 10% chance to occur. The chance is affected by Luck.
Using this weapon slowly drains the character's health.
===Arcanas===
Selecting Sarabande of Healing (VI) Arcana allows Muramasa's little hearts to heal 2 points of health and trigger a pulse dealing the same amount of damage.
Slash (XVI) doubles the damage of Muramasa's critical hits, causing them to deal 4x damage.
Divine Bloodline (IX) increases Max Health by 0.5 when enemies are killed with retaliatory damage.
Wandering the Jet Black (XXI) damage is increased by the healing generated by Muramasa. The draining effect counts as taking damage.

==Tips==
*Muramasa's ability to drain the character's health is useful for builds that is based on Sarabande of Healing (VI), Divine Bloodline (IX), or Wandering the Jet Black (XXI).
**For example, there is a synergy between it and Soul Eater; Soul Eater's power increases by healing missing health but enemies cannot reach the player because they are defeated too quickly, Muramasa provides that opportunity to heal up.
*The amount of health Muramasa drains scales with the character's health. This makes it a poor choice for characters that are able to scale huge amounts of Max Health, like Miang Moonspell or builds using Divine Bloodline (IX). At Max Health in the thousands, most source of healing beyond Disco of Gold (XV) with a Gold Rush will not be able to reliably sustain the health loss.
*The health drained by Mursamasa will also activate retaliatory damage from weapons. This can synergize with Divine Bloodline (IX) in order to scale Max Health even when enemies are no longer capable of damaging the player. 
*Due to the way it scales with Greed, Muramasa is a great pick for characters with scaling Greed, most notably Big Trouser, or high native Greed, like Je-Ne-Viv. Wicked Season (XIII) is also warmly recommended due to the way it scales Greed. 
*Characters with immunity to Health Drain such as Alucard have good synergy with this weapon as they are immune to it's major drawback.
==Trivia==
*This weapon is inspired by Muramasa. They were a famous swordsmith and the blades were favored by the shogen Tokugawa Ieyasu, but the katana gradually became a symbol of the anti-Tokugawa movement. Furthermore in lore and popular culture since the 18th century, the sword has been regarded as yōtō (妖刀, "wicked katana"), sometimes the blade spotting a blood red color, hence the blade's curse causing the character to lose health when using it.
*Its addition of finisher and critical hit is very similar to the effect of level 8 Victory Sword, the damage increase and cooldown reduction are also resembles the effects from level 9 to 12.
