I'm currently playing a Beguiler Wizard from Xanathar's Lost Notes to Everything Else and absolutely loving the firebolt sneak attack mechanics. For those unfamiliar, the Beguiler is a more wizard-y Arcane Trickster that gets bonus damage with attack cantrips if the same conditions of sneak attack are met. Super fun and flexible, excellent social skills, but not overpowered.
For my next build, I have to head back to my roots with a Bard and Xanathar's Guide introduces us to the School of Whispers and the Hexblade Warlock. Both use Charisma, and a few levels of Hexblade should allow me to attack using Charisma instead of Dexterity. I'd like to play him like Jarlaxle from the Drizzt novels, being highly charismatic, confident, sarcastic, and sly. I'm torn between creating a Half Elf for the obvious reasons, a Drow, a Half-Drow, or Human variant. I expect to be in hasted in most combats after I get that at 10th, and will likely fight using a hand crossbow most of the time (crossbow mastery) gaining sneak attacks via the 3rd level Whispers ability.
Of course, the real question is how long do I go before hopping into my Hexblade dip, and for how long? With 2 levels I gain basic Hexblade options, including the shield spell, and 3 cantrips (Green Flame Blade, Eldritch Blast, plus ??), two Invocations, three spells known (HEX, plus ??), and two free 1st level spell slots per short rest. Then of course there is the Pact, which I am now considering Pact of the Chain with Gift of the Ever-Living Ones for maximum healing, and Agonizing Blast of course.
Assuming this is 12th level with 10 bard and 2 warlock, I would be throwing out 5 attacks per round (provided all conditions are met). I'll be able to cast Haste on myself, so I could be using Eldritch Blast at close range, with no disadvantage, and then fire a hand crossbow as my haste action, and the crossbow mastery bonus action shot. Thoughts? Ideas and Suggestions are welcome.
I was thinking this for my next character, something like hex 5/ rest whispers for min/max or 6 hex for accursed specter and rest bard @ 12 for rp, you can steal a humanoids physical form and memories with bard and their soul with hexblade. Either way you want Eldritch smite, thirsting blade. 9/11 or 10/10 works too, start your day with 4 5th lvl spells and 4-6 more throughout the day.
