Fiend Warlock/Swashbuckler Help?

[Stormynight09]

Hi all, I've got a fiend warlock at 5th level with 2 levels in Rogue; I plan on going Swashbuckler but wanted to be sure I didn't screw up on anything; I took moderately armored as a feat for lvl 4 warlock. Not sure how many levels I should go into rogue/warlock further or what else I should add?
Aasimar (Protector)
Str 9 Dex 18 Con 16 Int 10 Wis 14 Cha 16

So far for invocations; I've got Agonizing Blast, Eldritch Smite, Thirsting Blade
Pact Of The Blade.

Any further advice?

OOOO Fun I love mixing in some Swashbuckler with the Cha casters.

I'd want to go at least Rogue 5 for 3d6 Sneak damage and Uncanny Dodge. Take the rest in Warlock.

Expertise should be in Stealth and Perception. I LOVE Mask of Many Faces invocation so grab that as soon as you can.

It kinda depends on your team composition. If you expect to get sneak attack often, then taking more levels is good. If you're unlikely to proc it often, then two levels might be all you need from rogue.
