Paladin Survivor Subclass (initial sketch)
Tenets:
I am a survivor: I survived in the face of extreme adversity
Bravery: I will not cower nor back down
Life: Life is sacred and fleeting so I will make the most of it
Triumph through survival: Evil cannot win as long as I survive
Channel Divinity: I will Survive:
You may expend your reaction to succeed on a saving through you otherwise would have failed
Level 7:
You have an aura such that once per day a person that would drop to 0 hp instead drops to 1 hp. This can be used multiple times per day but only once per person.
