Mastery properties
Each weapon has a Mastery property, which is usable only by a character who has a feature, such as Weapon Mastery, that unlocks the property for the character. The properties are defined below witht the following details:
Homebrew Addition
To give more options for martial classess, the folowing homebrew rules are implemented.
Replaceable Weapon Mastery
When selecting weapons for Weapon Mastery, you can also replace the Mastery property of any weapon you are using with another eligible property. For example, you could change a Longsword’s Sap property to Flex.
These changes only affect the character who makes them. If a Barbarian replaces a Glaive’s Graze property with Cleave, other characters using the same Glaive still use its default Graze property.
Repeated Weapon Mastery
When selecting weapons for Weapon Mastery, you can instead assign an additional eligible Mastery property to a weapon you already chose. A weapon can have no more than four mastery properties at a time.
If a waeapon has multiple mastery properties, you can only use one of them per attack. You must choose which mastery property you're using before making the attack.
For example, a Level 1 Barbarian could choose to apply either Cleave or Graze when attacking with a Greataxe, instead of selecting a second weapon for Weapon Mastery. Likewise, a Level 1 Rogue could choose either Nick or Slow for a Dagger.
