Hello there. I very much enjoy the set, and from reading this thread, it seems that the balancing of the ring in particular evokes some discussion. So I would like to give some perspective as someone who is a purely casual player.
For a little background, I have played for over 8 years now and have a legendary pet that I was able to acquire with next to no real money investment. Thus, I can permacloak and do all the fancy things other advanced players can.
When I see this ring, I just cannot help but think that this is legit one of the best rings I have ever seen. And when I say this, I am very much talking about almost every class. Why is this? Well, I am a casual player. I give not a single shit about dps, min-maxing or efficiency. All I care about is playing the game for the sake of playing it, but with this in mind, the ring slot has always been one to fuel specifically my survivability. I am one of the people who will only play ASS, simply because they like the weapon. I will play a shitty dagger just because it looks cool and gives me good vibes while playing. To me, this ring is utterly amazing. I would honestly play this, without much hesitation, on nearly any class, except priest (since geb ring is so easily obtainable) and Knight because of the amount of stuns I can dish out. Because I really couldn’t care less about a spellbomb more or less on my wizard. Because I don’t mind losing lots of dmg on my sorc. Because I won’t mind not being able to dish out an extra buff on my pally (especially since the removed the insta heal). All I see when I look at this ring is the fact that it provides not only exceptional survivability but also a significant boost in dmg, which I personally prefer atk over dex boost. Also, my favourite / main class is the rogue. If I could, I would never ever play another ring on rogue. Why should I? For the the brief time of visibility, this ring almost guarantees that I can survive any encounter, even if I really screw up, while also providing a significant boost to my damage, making it even easier to get soulbound damage in during the invisibility. Why shouldn’t I play this on wizard? Because I can drop a spellbomb less? Who cares?? I get a ton of HP with a great boost to def and atk! Who cares if I can deal more dmg when I can just survive much easier? Because dps rly doesn’t matter to me, all that matters to me is keeping my characters alive and getting soulbound. So why would the negative stats detract me in any way from using it? In my eyes, this ring has no negative stats. All I see is a shitton of survivability for the neglegible price of losing some ability-related dps. Like I said, the only classes I wouldn’t play this on are knight and Priest, but this is specifically because I cannot yet chainstun reliably without mp pots and more stuns actually matter to me still, and for priest I am solely focused on the survival of others, so in this case my own survivability is of secondary importance.
