Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Possible Non-PHB Subclasses

I would say Hexblade is sought after because of :

1) Medium armor prof, and martial weapon prof. Good to have, if you don't plan to multiclass. If you're going paladin/hexblade, then you don't really care of course.

2) Hex Warrior. But this is not the tip of the spear. This could probably be incorporated into bladelock. If however you are going two handed weapon and heavy armor route, then you still need 15 strength so that heavy armor does not slow you down.

3) Hexblade's Curse. This is why everyone wants it. A paladin/hexblade can double smite, with divine and eldritch smite at the same time. With Hexblade's curse, you can crit on a 19 as well as 20 for the cursed target. If you add Elven accuracy feat(on advantage roll 3 dice instead of 2), you have about 24% chance to crit on average.

4) Hexblade with Paladin can hit like a truck. Unfortunetely there is no middle ground yet. Other Subclasses of Warlock do not offer melee capability(or at least something that doesn't eat Eldritch Blast's dust by level 6), and even Paladin/Fiend Warlock, leaves things wanting. Hexblade was added because Wizards recognized that melee Warlocks just don't work as they should without it.

Also, if i may add, It's not for Wyll. Wyll is a fiend Warlock because he made a pact with a Fiend. That does not mean that Larian can't change the backstory to make him a Hexblade, but as he is now, he is a Fiend Warlock. If Hexblade is added, it will be as an option for us, because it's extremely popular, and because the melee lock lags behind without it. They could come up with another solution of course, maybe they will tell us more at the next PFH.

Since Hexblade is in Xanathar's book, we can't know if it's gonna make it. Maybe because of popularity, it's by far the 1st, but still, there is no guarantee.

For other subclasses, i would like to see the Wild Magic Barbarian, something other than Twilight Cleric(because it makes every other War Cleric obsolete), the Shadow Magic Sorcerer, or the Aberrant Mind Sorcerer, would fit thematically i think, the Conquest Paladin, the Bladesinger Wizard, and the Sword Bard.
