Coulby's D&D 5E build videos are great. And so much listenable. I have no doubt he'll make ultra efficient BG3 builds.
I was concerned, when seeing the video title and the fact that he specifically shows some multi-class builds, given we still don't know precisely how multi-classing will work in BG3. We may know roughly, but for an optimiser like Coulby, knowing precisely is what's needed. One thing in particular that we don't know, is how spell casting will work for multi-classed casters.
Well, at least he gave a warning before diving in.
I haven't reached the Cleric/Bard support character yet, so I'll see what he says. I suppose he won't his usual damage reports, and just outline the build idea, rather than evaluate the effectiveness.
