I fought Shade of Rahyeh for the first time yesterday and it was by far the most enjoyable boss fight out of the ones I have fought thus far.
I didn’t really consider the boss fight too hard because the mechanics were pretty simple other than the wing flap which was slightly confusing to figure how what the ground shading meant. After doing it 3 times I finally understood, the one shaded area is where he flaps and the other is where he is going to flap (please correct me if i’m wrong). Both are highlighted so you know the direction where he will turn. I found this mechanic slightly confusing and I felt like there would be an easier way to illustrate it for new players. Maybe have the section where he is flapping to be darker than the next section where he will flap. That was the only part of the phase that got me because I didn’t understand what was going on.
The boss fight for me personally was enjoyable because you had to be on your toes and quick to react to mechanic after mechanic. I found this fun and engaging but for new players this might be too much all at once because of how quick you are forced to switch to one mechanic to the next. I would suggest having 3 seconds maybe breathing room between the first couple mechanics to have a player understand than have the boss in “phase two” do them non-stop. I feel like going into this boss on a hardcore character would be extremely stressful (if you didn’t brief yourself on mechanics earlier) because you get little to no time to register what is going on. With how hard the boss hits, you need to help players learn what to do before spamming repeat on the mechanics. I would also like if there was a phase two to have the boss switch up what he will do next instead of it being in a cycle. Maybe have him sweep in a line more than once in a row. This would make the boss fight really interesting.
Overall great boss fight. Fun, rewarding. I also felt the potions granted were perfectly timed and were enough to sustain if you made some mistakes. Well done.
PS - The boss fight is a joke with Orian’s Eye. Hope that unique gets nerfed in the future.
