Bewitched Alonne Sword

The Bewitched Alonne Sword is a katana in Dark Souls II.

Availability
The Bewitched Alonne Sword can be obtained after trading the Soul of Sir Alonne with Weaponsmith Ornifex for 18,000 souls. To obtain the soul, the player must defeat the Sir Alonne in Memory of the Old Iron King located near the fifth bonfire in Brume Tower, The Smelter Throne.

Handling Notes
The Bewitched Alonne Sword should be treated with similar thought as Santier's Spear as it has a unique moveset which combines several attacks from other weapon-types into its own. Its 1 handed light attack, its two handed rolling and standing light attacks are not consistent with what you expect from other katana. Interestingly enough when power stanced it has what appears to be a "Longsword Power Stance Moveset".

When fully upgraded at 50 dex it has +197 scaling bringing its full attack rating to 377 making it the weakest of the katana family of weapons. It is fully buffable.

If you intend to use this as a main weapon for anything other than invasions you will need to remember it has poor duribility, Repair Powder (Dark Souls II) is a must.

Special ability
Rather than a parry the Bewitched Alonne Sword has a "Seppuku Buff" or "Blood Buff". When equipped in two handed mode and the "parry" button is pressed you will stab yourself, and damage yourself, in a unique animation  buffing the weapon for around 30 seconds after you pull your sword out of your body. Additionally the buff seems to add +40% damage to any strike during this time.

Moveset
Note: Same attacks are in both left and right hand.
