Alright so I still haven't beaten it so I might be missing something, However I got half way through the last phase alone so I think I have seen everything it has to offer so far. Also keep in mind, this feedback comes exclusively from an Air-water mage who thinks they are cool enough to solo a raid boss' perspective. So to begin with, this is the kind of boss I've wanted to see since I started getting a bit interested in game design, I always thought it was lame that final bosses were always "Beefy dude with tons of health and 4 generic spells" (such as Qira or Bob, I haven't fought any of them in a while though so that might have changed and I never knew). This boss was exactly what I wanted: -Unique set of spells and attacks -Not just a humanoid dude -Not a damage sponge (his health is pretty fair for what is currently a final boss and a raid boss, It took me about half an hour to get through the first 2 phases but I was alone and didn't have an insane DPS build so I think it was fair) Now, that doesn't change that despite being the kind of bosses I want to see, it has flaws. First of all, the first phase is too easy honestly, the only dangerous thing it offers is the retaliating gazers (the eye summon guys) and they are still too easy to defeat and deal with, which makes them nothing but a bit annoying. My suggestion for this phase is to make the spell rates a bit higher (except for the summons) and buff the damage of most of the spells, as aside from the summons, nothing he throws at you feels like a real danger. The transition to the second phase with the falling eyes is also fun but it has exactly the same issue as the first phase, it is just too easy so all I have to say is that the amount of eye bombs dropping should be buffed. Second phase is fine. I really got nothing to say about it I think it is pretty fun and it isn't a joke like the first one. Perhaps make the lazer, floor hole and bomb spells a bit more common? I think that would be a good buff. Over all, this phase was pretty good in my opinion, the difficulty is pretty fair, the damage things deal is fine, the level of chaos is also fine, not too easy like the first phase, not too crazy. The transition to the third phase is... pretty much the same as the first-second one honestly, it is fun but too easy, I say reduce a bit the time between each lazer wave. Now, the third phase. I'll be honest, I like a lot the level of chaos it has but this one is a bit too much. I think the difficulty is still fair because while it is way more chaotic than the other 2 phases, it isn't too excessive. I had a hard time finding a moment to attack though, mostly because the spawn rates for the summons is a bit too much for me. They spawned constantly and I had a hard time finding moments to attack since these dudes kept distracting me. I liked the wave-based summons from the other 2 phases over the constant flow from this one honestly. Now, literally the only thing that pisses me off from this fight: The wretches thing. I kept hearing about it and I didn't know what they meant but now... yeah ok, I see what they mean. I know my kit isn't very good, I deal about 5k only with every meteor after all. But these wretches are stupid, they have like 30k health and you have to kill them in 5 seconds. This would be fine if it dealt like 2000 damage but... It kinda deals like 9000, and that's essentially 90% of my mage's health, basically, I had to keep healing during that period just to resist the hits since it was no use to try and kill it. But then, the rest of the summon gang comes in to tear a portion of your health, which leads to a guaranteed one-shot from the wretches. I think the health or the speed of these needs to be toned down. A lot. Buff the damage to be a guaranteed one-shot but make it possible to kill with average level 90-105 gear or something because this definitely didn't feel fair, unlike everything else about this boss. So yeah, it gets a 8/10 from me, it is fun and unique, but it is too easy at the start and unfairly hard at the end. Buff first phase a bit, buff the transition phases and nerf the wretches.
