Was the character a Barb first or a Warlock first? By your title, it looks like barb first. At what level did the MC start?
So we have just started a new campaign at 3rd. They have had one session so far and he asked me if he could not change one of the levels to Warlock. Generally I am easy within the first two sessions on changing up a few things.
1) Will this player also want to cast spells or cantrips while raging?
Nope.
2) How, if at all, would this affect the advantage the player gains on Strength checks and saves while raging?
Not affected.
@
DEFCON 1 - I pretty much agree with you on this.
I have had a look at the both the barbarian and the hexblade class. There is no real mechanical benefit I foresee that would be an issue at my table. I personally think the player is building his character incorrectly, said as much to him. There are better ways to make the concept through Background, Feats, Skills, Bonds, Flaws and Ideals - including a makeshift
Patron Feat of sorts if need be. Failing that a combination of class features from the two classes.
As I see it the high Charisma is actually hindering him (points wise), he won't be casting offensive spells so he doesn't need the high DC and as for the Hexblade Curse minor healing it is not worth it if he only sees the character advancing to level 3.
Leaving the ability points in Strength actually works better since he intends to advance in Barbarian and Hexblade Curse works fine with that.
I think he is happy I said yes, but muddled that I provided so many possibly better options for building his character.
Thanks all.
EDIT: BTW @
Seramus your comment was awesome!
