With a paladin that don't have 13 STR (even with 13 CHA), you would indeed not be able to multiclass (unfortunately ðŸ˜) in any other classes, even if you meet the requirements for those others classes (so, in this case, 13+ CHA for Warlock).
Huh! That’s definitely something that I’d not picked up from the reading I’d done, so good to know! Thank you.
I guess it’s mainly academic as you’d tend to have the required stats in your starting class anyway, though I can see the rule could potentially catch out strength-based rangers as well as dexterity-based paladins. As well as some more out-there builds for other classes.
