Thoughts on Xanathar's feats

[Evaar]

I’m playing a variant of your Celestial Warlock build as a Tiefling and plan to take Flames of Phlegethos. Rerolling both hits of Greenflame Blade plus having the fire shield seems like a good time. Hoping it works out that way.

It’s very likely less optimal than what you posted, of course, but that wasn’t my goal.

I don't have a link, unfortunately. The analysis I did was for satisfying my own curiosity when building a Long Death character, rather than for a forum post.

Thanks for taking the time to elaborate! This was a great read!
