Paladin subclass
Vengeance
Single-target pursuit, advantage, and relentless mobility.
Vengeance starts by changing the normal Paladin play pattern through Oath Spells; Channel Divinity: Abjure Enemy, Vow of Enmity, giving the subclass its first clear mechanical identity.
Later features such as Relentless Avenger, Soul of Vengeance, Avenging Angel expand that identity at higher levels, so the subclass has a clearer role in combat, exploration, utility, or support.
