Need help building a Warlock

I create a serie of ilustrations of our characters, most of them in the same tavern (these are the 2 bards) My character is watching the girl play (already in love with her, even let the sword drop), while the other bard is in a fight because of a gambling:

" My character is already Fighter 1 / Warlock 2. I cant change its base now."

Probably should lead with that next time.

"Strength 16, Dexterity 8, Constitution 14, Intelligence 8, Wisdom 10, Charisma 17."

Well, if all your levels are a sunk cost, id say go all warlock at this point. Your charisma is higher and youre closer to maxing out cha to 20, which maxes your damage. Fighter lets you wear plate, and with a dex of 8, you need plate.

With a dex of eight, you need plate.

Trademarked by me.

Other than that, focus on eldritch blast and hex. Get spell sniper so you can attack when an enemy is next to you.  Prep for battle with the highest level armor of agythys you can cast.  Then you will dish out damage every time you get hit, and you dont take damage yourself.

The only other option that may make sense is if you go all sorcerer from here. Assuming youre level 3, 1 fighter 2 warlock. The advantage of sorcerer is more slots for armor of agythys and better aoe and control spells. 

The thing about most spell casters is their cantrips suck so they usually throw a weak cantrip or a slotted spell. The solution is usially a warlock dip for eb/ab and then save your slots for when you really need them..

You are already there. The 1 level of fighter is really the only level i would have avoided. So if you go all sorcerer from here out, eb/ab for free damage dealing. Spell sniper to use it in melee. And the rest in sorcerer for juicy spell slots for amor of agythys and more aoe options.
