My wife plays a druid, but she wants to stay a bit out of the way. How about a way to do that and not have to fire a crossbow? How about a spell?

Radiant is divine damage, not starlight. This is evocation but not considered radiant as I understand it.
It gets weird with radiant. I prefer radiant as divine only, but a number of star pack warlock spells/powers are radiant, and all of those are star based. I’d like to give the wizard a chance to play as well. But, I also put it at lower damage then the standard wizard cantrips too.
I haven’t seen that before. What is a star pack warlock?
