Blademaster
A human walks down a lonely road, a single longsword resting on their hip. From the ground a rumble is heard, and a bulette erupts up from the earth. An unearthly smile growing on their face, the human eviscerates the monster in seconds, letting it fall limply to the ground as the human continues on its face.
An elf fingers a knife at their belt, eyes darting all around them. A gang of surly orcs close in from all sides, their eyes gleaming as they ponder their delight in what they assume will be their next kill. Suddenly the elf lashes out, the dagger seeming to be propelled faster than the elf's arms could make it towards the lead orc. With a grunt, the orc swings their massive greatsword in front of the tiny blade, a look of disdain on their face. The two eye each other more cautiously now, aware of their equality, and that any mistake now could lead to their demise.
A tiefling mingles at a gala, smiling and laughing with the crowd. Now famous from their stint in the war, the crowd oohs and aahs at their glamorous longsword, sheathed in a solid gold scabbard at the tiefling's side. A scimitar suddenly flashes out of the crowd, the tiefling barely dodging it. They whip out their longsword, magical energy crackling along its length, but nobody seems to know who attacked. Nobody, save perhaps the smiling tabaxi, their assassination attempt unsuccessful, but their presence undetected.
Blademasters are very similar to the main three martial classes; the fighters, rogues, and barbarians that we know well; but rather than train themselves in any sort of variety they focus their studies to a needle sharp point, usually only a single weapon. However their dedication pays off, their lack of variety empowering them as they prove time and again that it's always best to prioritize quality over quantity.
Multiclassing
In order to multiclass a level in Blademaster, or take a level in another class if Blademaster is your base class, you need to have either a strength or dexterity score of at least 13. If you multiclass into Blademaster you gain proficiency in your choice of eithers daggers, greatswords, longswords, rapiers, scimitars, sickles, or shortswords (or if already proficient choose one for your Specialized Weapon) and Smith's tools.
Quick Build
You can make a Blademaster quickly by following these suggestions. First, strength or dexterity should be your highest ability score (depending on whether you want to use finesse weapons), followed by constitution. Intelligence should be your second highest ability score if you plan to follow the Spellblade Tradition. Second, choose the soldier background and select the Waterstance Stance.

- (a) an Explorer's Pack or (b) a Dungeoneer's pack
- Leather armor and smith's tools
Specialized Blade
At 1st level, you have honed all of your training into a single weapon, which is the weapon you gained proficiency with when you selected this class. This blade will be used in many of this class' features, and if you gain proficiency with other weapons (including weapons from which you selected when you chose this class) they are not considered a Specialized Blade unless otherwise specified. If you possess multiple identical weapons of the same variety that count as your Specialized Blade (such as having two daggers), choose one of them to gain the benefits of your Enhanced Blade. You can select a different weapon of that variety to gain the benefits of your Specialized Blade feature at the end of a long rest. If you possess multiple different varieties of weapons that would count as Specialized Blades (such as one rapier and one dagger) then one weapon of each variety gains the benefits of your Specialized Blade feature.
While wielding your Specialized Blade, you gain a +1 bonus to AC, attack rolls, and damage rolls. This bonus increases to +2 at 10th level, and +3 at 20th level.
Stance
Also at 1st level, you have learned a Stance, which is always active. Your Stance grants you certain benefits, and will gain additional features at 18th level. You can only have 1 Stance active at a time. You can have 2 Stances active at the same time once you reach 18th level in this class. You know 1 Stance at 1st level, and learn 1 additional stance at 9th level (2) and 18th level (3). When you gain a level in this class, you can exchange one Stance you know for a different Stance you do not know.
- Windstance: While in this Stance, you can take the Dodge action as a bonus action. At 18th level, you also gain advantage on your first attack roll each turn.
- Stonestance: While in this Stance, when you are hit by an attack you can use your reaction to reduce the damage by an amount equal to your proficiency bonus. At 18th level, you instead reduce the damage by an amount equal to your level.
- Flamestance: While in this stance, you deal an additional 1d4 fire damage with the first weapon attack you make using your Specialized Blade each turn. At 18th level, the extra damage applies to all attacks you make on your turn.
- Waterstance: While in this Stance, you can use your reaction when you are targeted by an attack to increase your AC by an amount equal to half of your Proficiency Bonus (rounded down) until the start of your next turn. At 18th level, the first attack roll made against you each round is made with disadvantage.
- Vinestance: While in this Stance, when you are hit by a melee attack, you can use your reaction to make one attack using your Specialized Blade against the creature that attacked you, provided that it is within reach. At 18th level, you take the Attack action using this reaction, instead of making a single attack.
- Smokestance: While in this Stance, you can take the Hide action as a bonus action. At 18th level, you also have advantage on dexterity(stealth) checks when you have moved no more than half of your speed.
- Riverstance: While in this Stance, your movement speed is increased by 10 feet. At 18th level, you don't trigger opportunity attacks when you move.
Enhancements
Starting at 2nd level, you've begun to Learn how to Enhance your Specialized Blade. Select one Enhancement from the Enhancements table at the end of the class description for which you meet all prerequisites (if any). One Specialized Blade of your choice gains the benefits of this Enhancement. You can exchange one Enhancement on your Specialized Blade(s) for a different Enhancement for which you meet all prerequisites (if any) at the end of a long rest. You gain additional Enhancements to apply to your Specialized Blade(s) at certain levels, as specified in the Enhancements column of the Blademaster class table. If you possess multiple weapons which are considered Specialized Blades, each Specialized Blade has separate Enhancements, the total of which cannot exceed the number of Enhancements for your level. You cannot take an Enhancement more than once, and Enhancements that enhance the same statistic (such as damage and attack rolls) can only be applied once, using whichever Enhancement provides a higher bonus. In addition, your attacks using your Specialized Blade(s) now count as magical for the purpose of overcoming resistance and immunity.
Multi-hit
Starting at 2nd level, you have begun to learn how to turn a flurry of hits into something attainable. When you take the attack action on your turn and hit with at least 1 attack, you can use your bonus action to make an additional number of attacks equal to your Proficiency Bonus. If any of these attacks miss, you do not make any further attacks using this feature, even if they would not exceed the maximum. You can use this feature a number of times equal to your Proficiency Bonus, regaining all expended uses at the end of a long rest.
Blademaster Tradition
At 3rd level you hone your skills using a certain Blademaster Tradition. Choose one Tradition between the Assassin Tradition, the Brute Tradition, the Ironscale Tradition, the Slayer Tradition, the Spellblade Tradition, and the Versatile Tradition.

Ability Score Increase
At 4th level and again at 8th, 12th, 14th, 16th, and 19th level, you can increase one Ability Score of your choice by 2, or two Ability Scores of your choice by 1.

You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses at the end of a long rest.

While invisible in this way, your movement speed increases by 15 feet, you gain a bonus to your damage rolls equal to your proficiency bonus, and have advantage on charisma(intimidation) checks against creatures that can't see you.

You can use this feature once, regaining any expended uses at the end of a long rest.
Ironscale Tradition
Those of the Ironscale Tradition seek ways to turn their Specialized Blades into a defense. After all, the best defense is a good offense.
Ironscale Defense

Versatile Tradition
Those of the Versatile Tradition believe that, although paring down is necessary to achieve perfection, having a small variety of weapons at your disposal can be useful.

You can use this feature once, and regain any expended uses when you complete a long rest.
