Thanks much for the reply! While there may indeed be a multitude of Giant Octopodes swimming out there somewhere I am indeed myself, good to see you here. I greatly appreciate all of the info, gives me a lot of stuff to review.
I also found a build from Shoka which looks to be doing similar things (Some players just want to watch the world burn ! - Sorcerer(-ess) (Arcanist + Demolitionist) Fire Albrecht Aether’s Ray), that Hexblade looks custom made for this concept which is awesome. Knowing there’s Conflagration out there to fill out the mid levels is fantastic as well.
Once I finish reading through the linked material I feel I’ll be in a much better spot moving forward. You’re correct in that gearing specifically to make OFF worth it isn’t really the direction I’m looking to go, which gives me a nice start in terms of points to spend on some of the other things you mentioned. I definitely like how much flexibility there seems to be in terms of respeccing, and am definitely looking forward to trying a bunch of things out. Again, thanks!
