paladin 17/warlock 3 is a nice combination
gives you 2 level 2 slots that refresh on short rest
eldritch blast with improvements
hex and a few other good spells
mage armor at will and summoning your own weapon
i have a halfelf paladin using this build, he is dex based and walks arround in robes and unarmed, he is a priest of sehanine, has the oath of ancients and his warlock pact comes from touching an artifact that had an archfey inside it
the archfey tricked him into making the pact disguising it as a ritual to sehanine, when the paladin noticed it was too late to undo the pact
The pally has a very elven theme, he uses armor of shadows invocation to summon a silver armor (flavoured mage armor), his pact weapon is a silver rapier with vines as the sword guard that dig into his flesh, when the paladin loses his temper the vines drain blood from his arm and the archfey takes over (the DM controls the character when this happens, i gave myself this flaw to compensate using a warlock pact on a paladin)
also my eldritch blast changes when the rapier is out, the projectiles become dark blue crescent moon slashes
i flavoured my character so much the party had a hard time actually understanding what my class was, i worked with the DM to be able to use my abilities by describing them without ever mentioning the actual name, since he had a copy of my sheet he knew which ones i was using
