Whether your enemy is made of stone and resistant to bladed weapons, or able to take to the skies far beyond the reach of spears and swords, as a weapon shaper you always come prepared. To others, steel is hard and unyielding, you you, however, it is as fluid as water. As you fight you've learned to watch for weaknesses and exploit those with the right tool.

Weapon Shaping

Beginning when you choose this archetype at 3rd level, you may use your bonus action to shape the weapon you are holding into any simple or martial weapon. The weapon takes on the appearance, damage, and properties of the weapon. The weapon regains its original form if you use this feature again, if you change it back (no action required), or if you go unconscious.

If it is a weapon that requires ammunition, you will also create 20 pieces of ammo of the appropriate type to the weapon you shape it. If you throw your weapon, or you are disarmed, you can use your reaction, on your turn, to summon it back to your hand. If it is a light weapon you may split the weapon into two of the same weapon with the same bonus action. 

If your weapon is magic you change its base form, but it retains any magical properties it had.

Adaptive Body

At 3rd level you’ve trained your body to adapt to any type of weapon and fighting style. As an action or at  the beginning of combat you can choose to reduce your Strength or Dexterity score. For every point you reduce one you can increase the other by the same amount. You cannot bring a score above 20 or below 8 using this ability. Additionally you can swap your fighting style with another. This change lasts until you take a rest and cannot be used again until you complete a short or long rest.

At 18th level the mastery over your body increases further. The maximum you can raise a score to using Adaptive body increases to 24 and the minimum decreases to 6.

Improved Shaped Weapon

At 7th level attacks made with your shaped weapon count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. Additionally, your attacks using your shaped weapon gain a +1 to attack rolls, this bonus increases to +2 at 15th level

    Additionally, when you use your weapon shaping you can choose to add or remove a property from the weapon. You cannot add the finesse property to a two-handed weapon or the light/heavy property to a light/heavy weapon.

Fighters Insight

At 10th level your you enter a fighter’s trance as you attack. You gain a stacking +1 bonus to your damage each time you use your weapon shaping feature in combat. This bonus maxes out equal to your proficiency bonus. You lose this bonus if you fail to use your weapon shaping feature on your turn or when combat ends.

Master of Combat

At 15th level you go into a flurry when you attack. When you take the attack action you can give yourself advantage on all attack rolls that action. Additionally, you can change your weapon before each attack roll. If you deal 3 separate types of damage you can make an extra attack as part of that action. You can do this 2 times and regain all expended uses on a long rest.

    Your fighter’s insight can stack beyond its maximum during the turn you use this feature. The bonus lowers back down to your proficiency bonus at the beginning of your next turn.

Weakness Exploit

At 18 level, your fighter’s insight increases to a +2 bonus to damage each time you use your weapon shaping feature. While at maximum fighter’s insight bonus you can deal extra damage equal to half your fighter level once per turn when you hit with an attack.
