Ruby zips up above the pair and hacks acid down on them. The first one avoids most of it but the second doesn't. The acid mostly seems to fall through them and both don't react except a quick glance upwards. Joe follows up with a few eldritch blasts on the first of the remaining creatures that tear away chunks of darkness. There isn't much left of it and before it can move the angel of light around Lurn lashes out at it and in a burst of light it is gone.
((No save needed, it was toast either way.))
The remaining creature also gets hit, but not nearly as powerfully. It recoils from the light as the light looks to continue to burn away its darkness even after the attack has passed. It hurls itself upwards and away from Lurn and everyone else around it into the night. Jolly and Celus swing at it as it leaps away, Celus just missing and Jolly hitting an arm but not appearing to do much damage.
((Attacks of opportunity from Lurn and Kroshav, if you would like.))
