oh, wow.. Githyanki have prof with medium armor? Nice. Guess you can skip mage armor then!
I personally spent the most time with my Drow fiend lock with Eldritch Blast funtimes.
Hex + scorching ray=death + shatter for aoe + misty step for getting away if needed and armor of agathyss for extra hp.
Now in EA I usually grab either 13, 15 or 16 points in dex depending if i plan to take moderately armored at lvl 4 etc (which also gives +1dex)
or just pump charisma to 18. (although you can do this with volos eye and hag hair)
With Githyanki half plate (overpowered) i get 15 ac + 2 from dex + 2 from shield. 19 total on a lvl 4 warlock.
As a drow you can also use the rapier from nere which scales from your finesse.
I made an adamantine shield too.
I somehow ended up making a fiend warlock hexblade-esque hybrid.
Although most of the time its just hexing and blasting.
