Weapon Master

Perfect Fluid Weapon Mastery

Weapon Masters are virtuosos of armed combat, treating every weapon as part of a single flowing discipline rather than isolated tools of war. Through relentless practice and deep understanding of balance, momentum, and technique, they can transition seamlessly between blades, polearms, hammers, and bows, adapting their style in an instant. The most renowned Weapon Masters elevate combat into artistry, blending precision, creativity, and mastery so completely that the strengths of one weapon seem to carry into the next.

As a weapon master you will be enabled to attack with a variety of different weapons in a single turn.
As you read this Subclass you will find conditions such as: '...on the same turn if (something-something) is done'.

Reactions usually sit outside of the character's turn. This part is provide clarification that there are some edge cases where you might use a Reaction on your turn and then you should treat it as part of your turn.

Edge case scebario example:
"The enemy rogue has readied an action when you attack them to bolt passed you trying to get passed your reach!"
"I use my Reaction and I do an Attack of Opportunity..."
That Reaction is on your turn since the trigger was when you attack them and should be part of the conditions of the special traits.

Level 3: Favourite Weapon

To others, mastery properties are limitations of design. To a Weapon Master, they are merely techniques waiting to be perfected.
A dagger can topple, a hand crossbow can push, and any weapon can become deadly in the right hands.

Through endless drills and relentless dedication, you have developed an unmatched connection with a single weapon — the one that feels like an extension of your own body. Choose one Simple or Martial weapon that you have Weapon Mastery with have it become your Favourite Weapon.

Whenever you finish a Long Rest, you may replace one mastery property of your Favourite Weapon with another mastery property available in the Player’s Handbook.
You may change your Favourite Weapon every time you level up and swap is mastery property if you want to.

Additionally, whenever you make a Performance check involving your Favourite Weapon, you may add your Strength modifier to the d20 test.

Level 7: Masterful Handling

Your relentless study of weapon forms and battlefield movement allows you to transition between arms with impossible fluidity.
Once on each of your turns, you may stow one weapon and draw one weapon without requiring any action (no action required),
treating the motion as part of your natural combat flow.This overwhelming focus on offensive momentum leaves little room for
defensive awareness. Whenever you swap weapons in this way, you cannot take Reactions until the end of your next turn.

Level 10: Master's Discipline

Your understanding of weapon forms has surpassed simple training, allowing you to wield each arm with flawless precision and control.You have learned how to position your body, shift your momentum, and exploit the perfect angle of every strike to draw out the full potential of your weapons.Your discipline allows you to execute even the most difficult techniques with effortless efficiency. Gain the following:

Heavy:You ignore the Disadvantage imposed by the Heavy property when wielding weapons you have mastery with, regardless of your Strength or Dexterity score with weapons you have mastery with.

Range: 

You no longer suffer Disadvantage on attack rolls made at long range with weapons you have mastery with.
Additionally, being within 5 feet of a hostile creature no longer imposes Disadvantage on your ranged attack rolls made with weapons you have mastery with.

When affect a target on your turn* with  two different Mastery Properties  (Cleave, Graze, Nick, Push, Sap, Slow, Topple & Vex) , that target has disadvantage on the first attack against you until the end of their next turn.

Level 15: Scholar of Arms

You understand the reach, balance, and flow of every Simple and Martial weapon, allowing you to move through combat with complete confidence. Opportunity Attacks made against you are rolled with Disadvantage.

This knowledge has become ingrained within your muscle memory, granting you unmatched freedom across the battlefield.
Your walking speed increases by 10 feet.

Whenever a creature misses you with an Opportunity Attack, as a Reaction you may immediately make an Opportunity Attack against that creature.
Alternatively, when a creature hits you with an Opportunity Attack, as a Reaction you may roll one of your Hit Die and gain Temporary Hit Points equal to the number rolled plus your Constitution modifier. 

Leven 18: War Dancer

You are feeling your weapon as a pulsating being and you are able to operate with it in combat as you are performing a skillful theatric play.

You can stow and draw your Favourite Weapon without spending an action (no action required or Masterful Handling required).

If you manage to deal damage to targets with three or more different weapons on your turn*.
Any friendly creature within 100 feet that can see you gets inspired and get a d10 dice they can use until the start of your next turn. The War Dancer inspiration can be treated like a Bardic Inspiration.

Until the start of the fighter's next turn when the friendly creature fails a  d20 test, the friendly creature can roll the War Dancer inspiration die (d10), potentially turning the failure into success. A War Dancer inpsiration die is expended when is rolled or when the Weapon Master starts their next turn.

*on your turn (clarifications are being provided on the top see Edce case scenario example).
