Need advice on what charisma class/subclass to choose
Hi, I'm the first time player, we're playing Abomination Vaults. Long story short I started playing as a rogue, but because I'll have to move I asked to try a different character to experience different abilities in pathfinder. Currently the party has a fighter, a barbarian, a wizard and a cleric. We lack any charisma based characters and I wanted to move there. I also really really love vampires and was thinking about taking an undead sorcerer. We also have free archetypes, but I felt that getting vampire dedication isn't beneficial for a caster on low levels.
My issue is that I read the comparison of different spell traditions and divine is considered the worst when it comes to damage, and both undead sorcerer and undead summoner use divine spell list, and we already have a cleric. What would be the best charisma based choice if the idea is an evil dhampir character, follower of Zura, with high charisma considering other party members, or having an undead sorcerer sounds okay?
