Arduin's Longsword

"A Cursed Longsword used by a Pursuing Knight who relentlessly went out of his way into hunting dow Madeline all by himself, his motives are unknown, even to you"

Bound Eternally. The Pursuer's Longsword senses whenever you have a desire to fight,to defend or to act for what matters, It manifests within your hand in the instance that you need it, however this also comes at a downside as you are eternally binded to this Blade, any other weapon you hold, it is replaced by the Pursuer's Longsword unless the Pursuer's Longsword is already in your hand and the other hand being free

The Pursuer's Longsword manifests itself into nearly anything that you consider a weapon aslong as you can wield that item and your instinct is to weaponize it, If it is any other regular weapon that you are proficient with, The Longsword does not need to roll anything for it to turn said weapon into it unless you cannot physically carry it, The Longsword only turns into materialistic things

If the item/weapon you attempt to weaponize is a magic item,weapon or item you cannot carry,worn,being used or carried by someone else,a magical manifestation or something that doesn't make sense to be weaponized, then the Longsword attempts to immediately transform said item into it, you must roll an Arcana Check where the DC is determined by the dm, On a failure, you are pushed back, compelled even as you take 1d6 + character level force damage, on a success, the Longsword changes into said item

You also make this check on simple things or other things if your mental intent is to specifically cause the Longsword to turn something unconventional or such to turn into a Longsword

You roll at a Disadvantage if the item or weapon is being used by someone else that is unwilling,it is stupidly heavy or it is magically protected by something and so on 

A Sacrifice i'm willing to make. Without using an Action or such, you may instead deal damage to yourself by 1d4+CON per charge to use if you do not have a charge or you wish not to use up a charge of your weapon

Surge of the Libertas. Without consuming an action or bonus action, you may grant yourself an Action Surge by expending atleast 5 charges, if you've already gained an Action Surge this turn, you may not get an additional Action Surge 

Maruvia's  Counterattack... As a Reaction to getting hit with an attack, you may increase your AC by +3 if it is a nonmagical attack, if it is a magical attack then the AC increase is by +5, you then consume 2 Charge upon use

Way of Zhan. As a Bonus Action, you may perform an Unarmed Strike at an expense of 1 Charge, you gain an Advantage if you have successfully struck your target

Proficiency with a Longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Bonus: Magic, contact with the blade, Damage, Combat, Versatile, Sap
