Potential Players Note:
I'm seeing a lot of overlap in the PCs submitted so far, caused likely by lack of knowledge of the other players characters abilites and also by inexperience with high level play.
Both the Bard and the Cleric are focused mainly on buffs/ debuffs and healing with limited combat oomph (barring the Bards 'charm/ dominate' effects) and the Sorcerer presented had no offensive damage dealing magic himself other than mainly 'charm/dominate' effects as well.
None of those three PCs could really deal any HP damage, and a monster immune to the Charmed condition or with Legendary resistances basically shuts them down completely.
If accepted 'as is' all three of those PCs would be rendered largely ineffective against such monsters.
I'm raising this to be fair to those players, avoid too much overlap, and for you guys to go back and have a look at your spell load outs.
Remember - we still dont have a Fighter, meaning the Rogue is currently the only damage dealer in the party!
