Carnwennan(C): The Knife in the Dark, this dagger allows their wielder to cloak themselves in shadows, hiding their presence from any who would wish to them harm. This concealment, is only effective in dark and dimly lit areas where there is ample room for shadows and darkness to thrive, but in areas with great amounts of light, they can be found much more easily.
Dyrnwyn(A): The Blade of Righteous Flame, this is the heirloom sword of the Shimizu family, a blade which only spares those with a righteous heart the cruel agony of it's golden flames. Rumored to have been blessed by Juno herself, the flames this blade emits are golden in color and do not behave like normal flames as they require no fuel to burn, nor do they harm that which the wielder doesn't intend to harm. These golden flames hold within them a holy light that burns the life energy of both demons and those who wield the powers of demons(such as devil Slayers and Satan Soul users). As such, this blade can't be used by Marianne while she's currently using any of her Satan Soul abilities, as the flames will actively seek to destroy the demonic taint that courses through her body, likely killing her n the process.
The flames that this blade gives off are intense even without the extra sting given to those with the ilk of demon-kind surging through their veins and can be controlled mentally somewhat to move in strange ways, though they can't take on a physical form without altering the blade to do so. This means that, if locking blades with an opponent, Marianne can have the flames whip out to strike her opponent's hand or perhaps their face/eyes if she's feeling viscous.
Skofnung(A): The Sword of the Madness, this blade bequeaths upon its wielder a great increase in their physical abilities and fighting prowess, however, they lose the ability to reason and fly into a berserker rage. While the blade keeps their fighting skills from degrading, it doesn't stop them from attacking anything in their way, be it friend or foe, thus it's best used when Marianne is alone. It's with this blade, along with her Satan Soul magic, that has led to the death's of many a Rogue Guild and given rise to her title of 'Bloody Mary'.
Gáe Buide and
Gáe derg(B): The Twin Roses of Mortality and Exorcism, these two spears make for a deadly combination when wielded skillfully. The Yellow spear, Gáe Buidhe, is a very dangerous weapon as not only does it inflict wounds the tend to bleed more profusely than normal, but they are incredibly hard to heal as well, as while the blood flow will eventually slow down, the wound will remain slow to close and heal as well as being highly resistant to the effects of healing magics. This magic effect can be bypassed, however, by nullifying the magic that is centered around the area. The Red spear, Gáe Derg, possess a spearhead with the ability to nullify any magic it comes into contact with, though for continuous effects, the magic can resume as normal once the spearhead is no long touching the affected area.
