Wait, I'm confused about some story. So, Nero was an Imperial that I fought in the raid with Gaius and the Ultima Weapon, right? He was Gaius's 2nd in command, but when we beat him in the raid, he fled and did not die. Then I see him at the crystal tower, taking aetheric measurements, right? He was the one taking the measurements the entire time in ARR? And then he does something heroic in The Crystal Tower.
So, he worked for Gaius, but had ulterior motives the entire time, is that right? The measurements he was taking weren't related to the Ultima weapon and were for his own agenda? Not necessarily an Imperial agenda, or? So Gaius is dead, but Nero is still alive and might possibly have a redemption arc after being saved by Garlond?
What does bait the orbs mean? You lead them into something? I've always tanked that fight and only ever noticed the ram/dragon mechanic. "Ram: outside, dragon: inside" might not be enough info for a sprout. You gotta remember some people are coming from totally different games or no MMOs at all. But usually people get it after 1 or 2 times taking damage lol.
