Blade of the Ashen Hills (5e Equipment)
From D&D Wiki
Weapon (katana), Legendary (attunement required)
This long, two handed ōdachi was forged by a once honourable paladin who broke his oath of mercy by killing an unarmed, surrendered opponent. For this his deity cursed him to be felled by his own blade, then to have his soul bound to the blade. When he did die, by falling on his own blade in combat, his soul violently exited his body in a fireball. Which charred his sword as it entered, giving the blade a smokey black colour and turning the red hilt wrapping burnt maroon. Frightened of what happened, a witness quickly sheathed the blade and tossed it into a volcano. However, over centuries it merely found its way into a mountain cave.
Tainted Steel On a normal attack the blade deals 1d8 slashing damage, doing an additional 1d6 fire damage on a critical. However, the user can sacrifice parts of their soul to the blade to enhance their strikes. In exchange for giving in to the blades curse the wielder can deal an extra 1d6 slashing and 1d4 fire damage untill the end of combat.
After prolonged exposure to the blade the wielders soul becomes corrupted, After either 10 successful attacks or 1 hour with the sword unsheathed the wielder gains one short term madness If you already have a short term madness, you are inflicted with long term madness. If you have long term madness, you are then inflicted with indefinite madness. it cannot corrupt the wielder when sheathed.
Sentience. Due to the bound soul the blade is sentient and is Chaotic Evil, as such only a non-lawful or a non-good aligned character can wield the weapon. It has: INT: 20 (+5), WIS: 10 (+0) and CHA: 25 (+7). It also grants advantage on Intimidation (Cha) rolls when the weapon is on your person. The sword knows Common, Abyssal and the languages of the user;The item communicates by transmitting its thoughts to the creature carrying or wielding it.
Personality. The mind inside the sword was once kind and compassionate, but as soon as he died his soul was forever tainted. He has long forgotten his true name, instead calling himself Pyre. He is malicious, manipulative, cynical and spiteful; admiring truly evil acts and people. He will try to convince righteous people to commit more sinful acts; such as killing captives, torturing enemies, insulting good people and other hostile behaviors. If its wielder doesn't give into its manipulations it simply waits for its corruption to twist the wielders mind.
