So, I was thinking over some party configurations, and the idea for a hybrid caster/melee character came to mind. Something with CHA as their primary mental stat, as well. Warlock came to mind.
Pact of the Blade allows the warlock to get Thirsting Blade, which gives an extra attack. Pretty much needed for a dedicated melee character. So with that and the warlock's casting, it seems to work out nicely at first...
Except...
First, this one is stat heavy, need STR or DEX for melee, (but I'm going STR), CHA for the casting. Okay, not the worst split. You can get medium armor proficiency with the sellsword background. However, you need to spend a feat on Raise Shield if you want shield proficiency.
That, and most of your warlock spells won't work if you have a weapon/shield, so you'd need to juggle your equipment. Not the worst thing to do that but it is still annoying.
Pact wise, the Tree seems easily the strongest. Having a kickback shield is pretty decent and you do get some bonus AC later. That and poison and necrotic resistance is handy.
It does seem like a pain to juggle everything, though. Though I'm not sure how much of an asset it is having all of Warlock's spells be keyed to short rests rather than long ones.
So, what do you think? Is a pact of the Blade melee warlock viable?
