The wall of light spell states:
When the wall appears, each creature in its area must make a Constitution saving throw. On a failed save, a creature takes 4d8 radiant damage, and it is blinded for 1 minute.
—Xanathar's Guide to Everything, page 170
The spell duration is "Concentration, up to 10 minutes," so the durations of the blindness and the spell itself are already different. Would this entailmean that the blinded condition it inflict would continue even if the spellcasterspellcaster's concentration ended the spell or were knocked unconscious?
