So upgrading weapons from 4* to 5* is generally not worth it when one does not have enough radiants to get it to level 10 or at least 7, right? And heating 5* shields is generally pointless because it won't add one extra hit's worth of defense right?
Does that mean upgrading a shield that isn't a snarboshield or heater shield to 5* pointless too? I'm asking mostly because Google failed me in my efforts to look for this specific question.
The status defence increases from taking some status damage to total immunity to status damage.
