In this video, I'm playing the highest tier boss raid out, being very hard to a majority of players who reach it, here I'll be helpful in providing guidance to beat it.
Congrats on the solo win. Tips are definitely helpful but here's some extra bits that you and others can also take in: For all the minions, don't bother trying to kill them since they take 2 (or 3 at most) cycles to kill and in the time you're running away from them, another attack will appear from the boss. It's possible to get them to attack and dodge the explosion but it's very difficult to do it. Many people don't realize this but all the hitbox positioning like the electric grid, the circles around the map, and even it's flamethrower are all in exactly the same spot and orientated the same way the entire fight. When you get to the phase where he loses his shield, you can just stay as far away as possible near one of the center walls because there's actually a tiny safe area for the spiraling circles which you may need to stay in at that point. Hope these help :)
I like the fact, that no matter how "Impossible" the boss will be, players will always find the way to solo it sooner or later. Cracking the Enigma Code.
