Lore

A cursed sword of unknown origin bearing uncanny streaks on its blade.

Attacks also damage its wielder.

The sword is not unlike a thing misshapen, granted life, but never welcome in this world. In other words, chaos itself.

Skill: Hold
Assume a holding stance to rapidly execute a lunging slash with normal attack, or a deflecting parry with strong attack.

Damage:	The Damage stat dictates how much damage the weapon does. The Damage stats for a weapon are A / B / C / D / E: A is Physical Damage B is Magic Damage C is Fire Damage D is Lightning Damage E is Dark Damage Each weapon has one or more Physical damage types: Standard Strike Slash Thrust Certain enemies are weak or strong against different damage types. See the damage formula for further details.
Aux Effect:	The Aux Effect stat dictates how effective the weapon will be at causing the effect. The Aux Effect stats for a weapon are A / B / C: A is Poison Effect B is Bleed Effect C is Frostbite Effect
Critical	Damage multiplier when performing a backstab or riposte. Value of 100 means no extra damage.
Spell Buff:	Damage multiplier applied to the base value of a Spell. This value scales depending on the primary stat of the Catalyst, i.e. a Catalyst with Intelligence scaling will have its Spell Buff rise as the player's Intelligence rises. By default the value reflected in the infobox and the upgrades uses 60 Intelligence and/or Faith.
Stats Needed:	The Stats Needed determines how high various Stats must be in order to wield the weapon effectively. The stats required for a weapon are A / B / C / D: A is the Strength required B is the Dexterity required C is the Intelligence required D is the Faith required Wielding a weapon without the required Strength and/or Dexterity will incur a penalty to the Physical damage of the weapon, while lower-than-required Intelligence and/or Faith will reduce the Magic/Fire/Lightning/Dark damage and Spell Buff.
Stat Bonuses:	The Stat Bonuses rating indicates the level of bonus damage you do with the weapon, based on the associated Stat. This rating can be S, A, B, C, D, or E (in order from most to least bonus for the associated skill). See Scaling for more information. The Bonus Stats for a weapon are A/B/C/D: A is the Strength stat bonus that influences the Physical attack of the weapon. B is the Dexterity stat bonus that influences the Physical attack of the weapon. C is the Intelligence stat bonus that influences the Magic/Fire/Dark attack of the weapon and Spell Buff. D is the Faith stat bonus that influences the Lightning/Fire/Dark attack of the weapon and Spell Buff.
Damage Reduction:	The Damage Reduction % of the weapon. It dictates how much damage the weapon mitigates while blocking. The Damage Reduction % stats for weapons are A / B / C / D / E : A is Physical Damage B is Magic Damage C is Fire Damage D is Lightning Damage E is Dark Damage
Stability:	Determines the amount of stamina expended to block an incoming attack. A higher stability also allows you to block stronger attacks without breaking guard and reduces the amount of stamina depleted from blocking attacks.
Durability:	The durability of the weapon.
Weight:	The weight of the weapon. Note that carrying over 70% of your Equip Load will reduce the speed of your rolls, while going over 100% will reduce your regular speed to walking and attempts to roll or backstep will leave you momentarily stunned.
