I'm intending to play something like the Celestial Warlock build in DotMM. I put my own variants on it that likely de-optimize it somewhat but make the flavor a little more compelling to me - primarily, I went Tiefling (Glasya) and started with odd scores in both Con and Cha with the intent to even them out by taking the Tiefling racial traits.

I'm sure the Variant Human version is more optimized, but the rest of the group is pretty new to 5e so I don't want to constantly have the spotlight. Primarily what I'm looking to do is be able to function effectively in whatever role we need at the time, since everyone else is still pretty timid and uncertain about what they should be doing during fights. I'm looking forward to it and will report back how it goes.
