3rd: Convenient Scabbards

You can draw and stow any number of weapons on your turn, requiring no actions by you.

3rd: Special Techniques

Learn two of the following skills at 3rd level, and learn an additional skill at 5th, 10th, and 15th level.

Swordfaire: Once per turn you gain a +1 bonus to your attack roll made with a sword weapon. When you strike a creature with a sword weapon, you gain a +2 bonus to your armor class to attacks made by that target until the start of your next turn.

Polearmfaire: Once per turn, you gain a +1 bonus to an attack and damage roll made with a polearm weapon. When you strike a creature that is prone or more then 5 feet away from you with a polearm weapon, you can deal an additional 1d6 damage.

Axefaire: Once per turn, you gain a +1 bonus to an attack and damage roll made with an axe weapon. The first axe attack you make on your turn scores a critical on a 19-20.

Macefaire: Once per turn, you gain a +1 bonus to an attack and damage roll made with a mace weapon. When you strike a creature with a mace weapon, you can push them up to 10 feet.

Flailfaire: Once per turn, you gain a +1 bonus to an attack and damage roll made with a flail weapon. When you hit a creature with a flail weapon, you can use a bonus action to knock the target prone if they are your size or smaller.

7th: Combo

Once per turn when you hit a creature with a weapon attack, you can choose to gain advantage on your next attack roll if you make that attack with a different weapon.

You can use this feature an amount of times per rest equal to your proficiency bonus.

10th: Bowfaire

You do not have disadvantage when using the long range for thrown weapons.

Once per turn, your bow or crossbow attack gains a +1 to attack and damage rolls for each of your weapon attacks that hit the target on that turn.

15th: Superior Mastery

Once per turn, you can grant an additional bonus to one of your weapon techniques.

Sword Weapon - The target of the attack cannot make opportunity attacks against you until the start of your next turn.

Polearm Weapon - Grant the attack 2d6 additional damage if the target is prone or more then 5 feet away from you.

Axe Weapon - The attack can score a critical on an 18-20.

Mace Weapon - Push the target 15 feet back.

Flail Weapon - Allow the attack to ignore any shield bonuses the target has.

18th: Finishing Blow

When you use the attack action, you can potentially make an additional weapon attack as part of the same action. Each of your attacks must be made with a different weapon category and must hit the same creature. If all of your weapon attacks hit that target, you can use a different weapon to make an additional attack against that same target.

Ex: If you make an attack with a lance weapon and hit, then a sword weapon and hit, then an axe weapon and hit, you can make an additional weapon attack with either a flail weapon or mace weapon.

At level 20 when you unlock extra attack (4) you must use a different weapon from each category in order to make all 5 weapon attacks.
