Ok, but while you spend your upgrades on wands of prismatic light, I use them on armor and weaponry and just kill them. And the enemies still pathfind towards you while blinded, so you can’t even attack melee enemies that way. I will keep using wands that don’t need upgrades to be good, like fireblast, corrosive, blastwave and transfusion and you keep +15 your warding but dying to monks and golems
