Greatest Greatsword and Bucketest Bucket

Prestige 1-2 Work anywhere

The Sword of The Tanku: During tanku's fight to save Hugh she became a sword, One sword to rule them all. By concentrating she turned a part of herself into a blank sword,  A perfect slate. And then she threw the rest of the swords in...

Once Per Day Tanku can create her ultimate sword, By combining two or more blades tanku can create a new sword. The new sword mergs their properties, abilities and effects. For each sword combined the sword increases by one side up to Gargantuan. The sword count as one sword for the purpose of attunement. Tanku can choose to ignore any negative effects from the merged sword if they choose.  Great sword's Keep their respective charges, and each greatsword can only be added once. The sword stays in this state until it is dropped, un-merged or Tanku dies. When this sword is un-merged the greatsword's fall to the ground in a bucket like shape. 

Greatswords of Unbelievable Power: Tanku has found swords of such mythical power when they cannot control them for long, yet the follow. Upon entering combat, 4 mythical swords appear around tanku as a free action once per turn, she can grab one and activate it. A sword cannot be used again until all others have been used:

-Time Blade: When this blade is activated Tanku cuts out a segment of the passage of time for himself severing it and its consequences from reality. Tanku is reverted to the exact state they where in at the start of the current round of initiative. with the health, effects and resources they had at the time.

-Ockham the Razor: In philosophy, Ockham's razor is the problem-solving principle that recommends searching for explanations constructed with the smallest possible set of elements. the wizard Ockham himself inserted his mind into this blade, it holds the power to reject any reality that is not simple enough for his "narrative" thus one slash from it renders magical effects null and void. When this blade is activated the sword is swung and all magical effects within a 30 ft radius of where tanku is standing is cancelled as if a ninth level dispel magic was casted on it. no magical effects can be caused in that area again until this sword is used once more. (The magic from greatswords is not cancelled since Ockham considers them simple, being a greatsword himself)

-Atom Splitter:Crafted by the best artificers from seven realms, the atom splitter is a sword made specifically for one thing, the destruction of an atom. its blade is thinner than a single electron giving it the ability to cut an atom in half releasing its energy into the world and causing a fission reaction. when this blade is activated tanku cuts an atom in half causing a nuclear explosion centered on him. each target in a 250 foot radius other than tanku must make a 35 dc dexterity saving throw or take 15d10 fire damage and 15d10 radiant damage and are pushed 200 feet away from the center of the explosion. on a successful save the target talks half as much damage and is only pushed 100 feet distance from the center.

-Ouroboros fang:Forged from a fang of the Ouroboros knocked out during its fight with the god of thunder, the former user of this blade ended up being trapped in the same day for 10 years before being able to escape. He handed the blade to the god of greatswords himself as he himself couldn't manage that power When this blade is activated, One person tanku can see within 30 feet must make a dc 33 charisma saving through or have the mark of infinity appear above their head for one minute. While the mark is above there head they must use the last action, bonus action, and reaction they used. For example if a wizard casted fireball at 8th level, they must continue to cast fireball at 8th level until the minute is up. If a person cannot physically complete the action. (for example the wizard runs out of spell slots) the symbol of infinity breaks. The ouroboros fang Always completes its loop Causing a spectral version of the target to appear. Repeating the action for the rest of the minute but now targeting the one who broke the mark of infinity.

-Continental Crusher: Geologists have been confused for years as it seems that at some point during the Jurassic period, one of the tectonic plates of earth simply disappeared. Little did they know a primal demigod sword-smith shaped and forged it into his ultimate creation. A great sword that was barely a sword and much more a slab of mass and tectonic energy fused into a single chunk attached by sovereign glue to a stick from the world tree. Only the god of greatswords could even take it up. When this blade is activated tanku swings it down onto his enemy attempting to crush them with its share mass and raw primal power. On a hit the target takes 10d8 Bludgeoning Damage. And must make a strength saving throw DC 33. On a failed save, the target takes an additional 30d8 Bludgeoning Damage is propelled downwards tearing through the earth. The target is pushed 1000 feet downwards. Leaving a hole just as wide as them in whatever material they are sent through.

 
Prestige 3-4

**Ceaseless Edge: Duel**

As an action tanku can concentrate their energy into a great sword they are holding and make an attack against a target, on a hit the great sword releases the energy and pulls tanku and the target into Tanku's personal domain.

The domain is seemingly made up of a near infinite amount of swords filling up the sky above and the ground below. Upon being pulled into the domain the target and tanku are locked into a duel and must follow the following rules:

• both targets must be holding a greatsword. If either target does not have a greatsword to immediately draw a mundane greatsword will appear in the targets unoccupied hand, if no hand is unoccupied they must immediately stow an object they are holding for the greatsword to appear. If they Are not currently holding a greatsword they cannot take actions or move
• Both targets must stay within a 50 foot radius circle, when they appear within the domain both tanku and his target appear on two opposite sides of this circle.
• Tanku Loses their godly protection within this domain. Making it possible for their own permanent demise. This increases the strength of the domain, it will only release tanku or the target if one of them falls unconscious or dies. The domain lasts forever otherwise.

The Blades Tempest: Tanku can cast their many greatswords into the air forming a tempestous storm. At the start of their turn tanku can cast the blade barrier spell without a action. (Save DC 25 ) with the following modifications:

° The spell does not require concentration

° The spell deals an additional  15D10 slashing damage

° Tanku can render themselves and allies immune to the spells effects

° If the spell is cast as a ringed wall it can be centered on tanku and follow him as he moves.

Tanku's fighting spirit has become so strong it persist after death, If tanku dies. they are killed and a spirit of pure need to fight and kill will appear, killing everything within its path. It has all the abilities of tanku and their godboon, and fights almost like a beast. The only way to undo this state is to defeat the Fighting spirit, and use wish to revive Tanku.
