Six, so fair on that point, that works once, Hunter resurrects and changes his strategy to kill the drinker before it can look at him.
Resurrects? The ability doesn't kill by itself. He just gets incap'd. The Vitreus Drinker wouldn't want to kill immediately, it wants knowledge for Vecna. After getting incap'd, it's free real state for Detect Thoughts, potentially learning about the rewind. And that's assuming the Hunter gets to know it needs to stop being seen by the creature, assuming the creature doesn't keep abusing its hit-and-run tactics (as it is his standard tactic).
The one you thought it was Eyebite. The one that renders the Hunter blind.
What? The Drinker has multiple abilities that require concentration: Detect Thoughts, Arcane Eye, Eyebite, and Vampiric Touch are all concentration spells
Only DT requires concentration.
Arcane Eye once activated it's free. Eyebite it's free, already linked it.
Vampiric Touch it's instant, by definition can't be concentration.
Cool? How does resistance negation make any difference when the opponent's eyes are obstructed?
Horrific Gaze or whatever of its spell-like abilities now affect the Hunter. But since it doesn't resist Horrific Gaze in the first place, doesn't really matter.
How would that help though?
Studying its opponent. Look at the intelligence of the Beholder, the Vitreus has greater intelligence than it.
That wouldnt permakill the Hunter though, he'd just resurrect and adjust his strategy to kill the Drinker before it can use that.
Doesn't need to. Keep spamming it and GG.
It wouldnt no, even in-game Deflection isnt all that useful, and the Hunter can just use an AoE weapon if need be. Even the Drinker's profile notes it as 'somewhat deflects attacks'
This is incorrect on almost every level. Deflection is a passive forcefield. If the Hunter can't bypass it, he ain't even hitting the Vitreus Drinker.
'It would, but at the same time the Drinker would need to focus specifically on The Hunter as Eyebite is a single target concentration spell, if it focuses on any of the Hunter's summons then it leaves itself open to being ganged on by the rest of the team
The Vitreus Drinker can already fight summon-spammers (multiple, in fact). Also, how are they bypassing Horrific Gaze exactly?
How does that give skill exactly?
Doesn't give skill. What it does give is Vecna constantly telling it what to do. Specially useful against the time rewind, as Vecna would now be aware of it and would want to get more knowledge about it, instructing the creature what to do to gain said knowledge.
