Yes...and that was explicitly one of the things the poster cited. Being able to nova so hard it startles the DM.I read it different. Versality is power. Having the ability to nova once in a while is power.
Yeah...and Barbarian isn't that much better at it than a Hexblade/Paladin multiclass.Sustained damage is a different kind of power, which is porably the barbarian and the pure paladin´s expertise.
From 2016, when Sage Advice tweets were still considered official, the answer is yes, you can. Which makes sense, since Eldritch Smite is literally identical to baseline Divine Smite except with a superior damage type (force vs radiant) and knocking most targets prone.Warlock Hexblade (including the shield spell you seemed to be unaware of) is undoubtedly a very strong multiclass option combined with paladin, especially if you interpret the multiclass rules that you can power smites with warlock spells, which is not cristal clear, as multiclass rules only allow cross casting of spells between spellcasting and pact magic, and I tend to say, it was not designed that way (the first printing of the PHB explicitel spelled out paladin slots for smiting).
The crux of my response here is the following:
1. Two of the three parts of this multi-multiclass are much stronger for MC than any other option. The third is weaker, except that they chose the one subclass which compensates.
2. The poster downplays things and speaks about versatility....and then takes pride in the power they can employ.
3. Even given all of that, I'm skeptical because this is an 11th-level character making use of 5th-level-or-lower features. That's a pretty big gap, and if the DM is actually getting caught with their pants down despite it, that seems to say more about the DM's actions than the player's.
The vast majority of multiclass combos are a downgrade in 5e, and of those that are not, most are one-level or three-level dips. Versatility is rarely actually worthwhile, unless the versatile bits align quite nicely.
I don't want to demean or downplay the poster's experiences. They're having fun, and that's great. But their experience is objectively not representative of most multiclassing choices, and even accounting for that component, I strongly suspect that there are other reasons their experience isn't representative.
