Yes, that is a bit of an existential rabbit hole, to be fair. I would assume that they are there to give players a reason to move out of the way & focus on doing something other than DPSing the boss.
That’s trivial to deal with. If you stand slightly to one side of centre, when he does the sweeping eye beam he’ll sweep it from where you are towards the nearest edge. So if you’re slightly to the right of centre, he’ll do his sweeping eye beam from a little to your left through where you’re standing towards the right edge. So all you need to do is move to the left side of the screen & you’ve avoided it without any movement skill. If you wait for too long (ie, when he actually starts the beam) then yes, you’d be hit & likely oneshot but there’s a lot of time between when Lagon rears back & his eye goes red (this is when your position is “locked in”) to when the beam starts.
Quite possibly. My premise is that I don’t believe there are any, or many, boss attacks that require a “normal” movement skill to move out of (I’m not counting Julra’s big AoE explosion as that’s designed to be escaped with the time shifting skill)).
From memory, all of the monolith bosses’ attacks can be walked out of, though obviously they’re easier to use a movement skill to move out of.
- Fall of the Outcasts, the only one that might “require” a movement skill is if you’re melee & you kill the soul vessels & the area around them fills up with Necrotic DoT.
- Stolen Lance, you can get out of all of Argentus’ attacks without a movement skill
- Black Sun, the void DoT line is easy to avoid/position & the “pie attack” is easier to do with less movement speed (since you can go around it closer to the boss)
- Blood, Frost & Death, can’t think of any big attacks that need a movement skill, the big line attack thing has a lot of wind up time to allow you to get out of it
- Ending the Storm I’ve already covered
- Fall of the Empire, as above, you can walk out of all of the AoEs
- Reign of Dragons, I’ve done with 6% movement speed & that was easy
- I can’t think of any big attacks from the newer 3 that require a movement skill either TBH
- Even Majasa’s petrify can be walked out of if you’re in melee range
If you disagree, fair enough, but which ones do you have difficulty with (apart from Lagon’s sweeping eye beam)?
