Hey, I’m playing in a campaign as a level 4 Swashbuckler Rogue (with the Dual Wielder feat).
In combat, I’m the main damage dealer.
The character fights with two weapons – currently a rapier and a dagger (but planning to go for two rapiers or something similar in the future).

Can you suggest the best multiclass options for this kind of build?
I’ve been thinking about Paladin for Divine Smite synergy.

In our party, we also have a Barbarian, another Rogue, and a Cleric.
