I have recently joined a 5e campaign and I was thinking about making a Sorcerer Rogue multi-classed character. Before I commit to that character build, what are the pros and cons of multi-classing in the 5e stystem that apply to mixing those two classes: Sorcerer and Rogue.
The main disadvantage seems to be that ability score increases (ASI's) are tied to class level in 5e rather than character level, so you really need to keep your multi-class levels in multiples of 4 in order not to lose this important feature.
Spell casting is another major thing, especially for a sorcerer. If you don't multi-class with another spell caster you will lose access to spell slots, which I understand is pretty important for a Sorcerer.
One advantage is that you will have a more varied array of options available to you.
One disadvantage is that those options will all be of a lower level than you could have had if you stuck to a single class.
If you take 10 levels of one class and 10 levels of another class you will have twice as many level 10 and level 5 class features to use, but you won't have any level 15 or level 20 class features.
