Paladin -> The protector -> Redirects 50% of the damage that would be inflicted on another creature on you. You can use your standart saving throw based on damage type to avoid it. -> 15meters ( you cast it when the fight starts and move away) : once per long rest. 
Barbarian -> Scream of fear -> Force enemies to flee(unless succesful saving throw based on conddition)  or attack the barbarian for 1 turn with lowered accuracy(saving throw based on condition)  . Once per long rest. Radius: 5 meters. Maybe 10. 
Bard -> Song of the flayer  ->  Increases affecte creatures intelligence by 2 for 3 turn. Radius 5 meters. -> Once per long rest. (Could help in intelligence saving throws against mind flayers and drow spells). 
Sorcerer -> Innate power  -> Low level spell sequencer ( do they still exist in 5th edition ? ) -> Up to 2 sdpells of lower levels can be "saved" and thrown in one go. Once per long rest.
Always fun to speculate.
