Base Class: Rogue
It's a bird! It's a plane! It's J Jonah Jameson's worst nightmare.
Astonishing Demeanor
Starting when you choose this subclass at 3rd level, foes are disheartened to see you. When you make an attack against a surprised creature it and any other surprised creatures must succeed on a Wisdom saving throw (DC = 8 + your Proficiency Bonus + your Charisma Modifier) or become frightened of you for a minute. Using this ability reveals your location to any creature that makes the saving throw. A frightened creature remakes the saving throw at the end of each of its turns.
Bonus Proficiencies
Also at 3rd level you are proficient with Disguise Kits, as well as with attacks made with improvised weapons, which can benefit from your Sneak Attack feature.
Amazing Courage
Starting at 9th level you make all saving throws to resist being frightened at advantage.
Extraordinary Menace
Beginning at 13th level, improvise weapons deal 1d8 damage to creatures that fear you.
Fantastic Influence
Starting at 17th level, your fearlessness is inspiring. Allies within 30 feet that can see you can add your Charisma modifier to saving throws made to resist being frightened.
