Ah, a pleasure to meet someone with similar taste 😄 I'm actually with you on the Celestial Warlock. It's also up there on the list of sub-classes that I've an interest into.
I like throwing out some reliable DPS, but I also enjoy healing. "Offer one hand, arm the other" is my personal motto.
A good motto! And yes, healing or most sort of support are nice :p
That being said, I'm currently making a build for an
Archfey Warlock...and, oh my, I love it 💚!!!
I hope Larian implements it, and implements it well : meaning with the Pact of the Tome, Book of Ancient Secrets, proper rituals and if they make us choose a patron, allows us to pick a non-evil one (Neutral will do).
