Hmmm... 6d10 for moonbeam if upcast to level 3 vs 8d6 fireball one time...
I'm failing to see how moonbeam isn't OP in its current state. The issue with moonbeam is that it hits targets twice, once when cast on your turn and again on the targets turn. It should not do this. There's no way they don't fix it on release. It's brokenly OP.
Yes, I'm still struggling to avoid this conclusion too.
I've found some info from 2016 suggesting Moonbeam should only do damage at the start of the enemies' turns. p15 of the WotC Sage Advice at
https://media.wizards.com/2016/downloads/DND/SA-Compendium.pdf says "Does moonbeam deal damage when you cast it? What about when its effect moves onto a creature? The answer to both questions is no". It goes on to explain why and lists some other spells including Cloud of Daggers that should work the same way. But that's quite a long time ago now, so perhaps there's some more recent guidance that says otherwise? If not, then Moonbeam in BG3 isn't currently working as per RAW, but even if the guidance has been updated I think I'd prefer that 2016 version
.
