Hi all I'm making a aasimar summoner/healer and am having trouble figuring out how to best go about this. I'm using the unchained summoner and the eidolon is an azata and I want to multiclass into either Paladin or Oracle maybe cleric if it's good. Character will start at lvl 3 and probably go to lvl 20 if the campaign lasts that long and the setting as far as I know is horror in the city. Goal for the summoner half is aasimar calls upon one of their relatives to help them fight while the summoner themselves runs around keeping everyone healed up and buffed if possible. Feel free to give advice for other possible options that can still achieve this.
Tl:Dr aasimar heals while their summoned angel cousin fights things. How do I do this
