I am planning on playing an Oath of Conquest paladin, and I really want to capitalize on the Aura of Conquest feature (XGtE, p. 38):
Starting at 7th level, you constantly emanate a menacing aura while you're not incapacitated. The aura extends 10 feet from you in every direction, but not through total cover.
If a creature is frightened of you, it's speed is reduced to 0 while in that aura, and that creature takes psychic damage equal to half your paladin level if it starts it's turn there.
At 18th level, the range of this aura extends to 30 feet.
Besides my Conquering Presence Channel Divinity option and spells I have access to, are there any other ways I can frighten creatures?
