SV-3 Eradicator

This boss is very easy if you can master his Red/Blue beam mechanic. This is how it works.

If you target the boss before engaging him, you will notice that he has 3 buffs. Two of those buffs deal with the Red and Blue beams he shoots. The buffs coincide with how many pillars are lit up of that color. So, if there are 4 red pillars, then he will have the red beam buff x4 and blue beam buff x2. Now, if the boss shoots a red beam, it will be amplified by the number of red beam buffs he has on him. I hope that helps clarify how the mechanic works. This is how we accomplished this boss after a little trial and error.

Group setup: Jug Tank, Merc Heals, Op DPS, Sorc DPS

We assigned the heals and the tank each one pillar. The healer took the back right, the tank took the back left. Each of the DPS got 2 pillars. Op took the 2 front left, Sorc took the 2 front right. We all got into position around the boss relatively close to our pillar. We pulled the boss. When the boss began to cast his beam, we would observe which color beam he was attacking and ensure that all the pillars were the opposite color with each person being in charge of their assigned pillars. The cast is long enough that this is possible if everyone is paying attention. And generally, it tended to go back and forth; however, he did cast the same color more than once in a row. If you do this correctly, there will be virtually no damage to the team occurring. It's as simple as that. The only other ability he does is a knockback with a snare which is dispellable. Rinse and repeat on every beam cast, and you are good to go. It will be a bit of running around, but if not done correctly the beams can one-shot the person it is targeting.

So, to sum it up, make sure that all the pillars are the OPPOSITE color of the beam the boss is casting and the beam will do no damage.

There wasn't any help for us when we did this, so we came up with this after a couple attempts. In retrospect, we probably could have had the healer do two pillars and leave one of the DPS for only one pillar so that DPS would have been higher. I say this because, since we pulled it off correctly and always had the correct color on the pillars for his beam cast, there was almost 0 group damage.

Hope this helps someone!

I don't know if I'm just failing miserably, or if the encounter has become bugged. I have been soloing Red Reaper, trying to find a particular orange or two. My sole hangup is bad luck on SV-3. I'll have it at, say, two blue and four red, and it starts charging its blue beam. I think, okay, even if it targets Tharan, I'm fine - Tharan can live through a two-buffed beam. At the last moment of the cast though, all of a sudden all six pillars are blue and it one-shots Tharan. If it targets me, I can survive anything *but* the six-buffed beam. I won't even bother to change it if it's five-buffed. But then again, it changes at the last second when it's too late to do anything about it but die.

That can't be working as intended. If a boss has a one-shot mechanic, there has to be a way for players to avoid it, and the way the pillars are changing you can't always do a damned thing about it. So either I'm still doing something wrong, or the encounter is bugged.
