I would love to be able to have different color options for the animation of three specific spells :
1) Magic Missile
2) Eldritch Blast
3) Faerie Fire
Agreed this would be a nice touch, and those spells (particularly Magic Missile and Eldritch Blast) are the ones that would most benefit.
I do like the idea that the colours are driven by subclass, so for example your dragon sorceror could have missiles the appropriate colour for your dragon ancestor. But I guess accommodating decisions that are head canon rather than determined by the game, for example to create a wizard who focuses on lightning spells, would require letting the user pick.
In short, not a biggie for me, but if there is a way for Larian to introduce something like this cheaply then I would appreciate it.
If they can’t, it’s great to know that modders are already on the case!
