Best spell options for Aberrant Mind Sorcerer.
I've recently started playing Curse of Strahd campaign as a montain dwarf Aberrant Mind Sorcerer and I'm in two minds about what spells I should take further down the line, especially when it comes to the subclass spells.
Right now I'm playing at 2nd level and I have shield, sleep and magic missile prepered, as well as the default two spells (dissonant whisper and arms of Hadar), in a session or two we'll be reaching level 3.
My original idea was taking silvery barbs since by 6th level I'd be able to cast it for a single sorcery point, which seems really good, but DM decided to ban that spell.
When it comes to the rest of my party we have a rogue, a bard and a light domain cleric. Dissonant whispers has already came in handy for double sneak attack synergy. From what I've gathered CoS is undead-heavy campaign so that should probably affect what I pick.
I'd also appreciate feats suggestions, I'm at 14 dex, 16 con and 17 cha.
