Bismark Ex is doable blind

Ravana Ex is doable blind

Sure, if everyone else knows the fight and you get carried. Bismark is the easier of the two so I'll use that. In Bismark HM you were thrown off his back safely. There is no way to know that this is impossible. I guarantee that the first groups to do this fight had their first failures here. There is no cast bar and no debuf to read. He behaves exactly the same as in HM and if players' only knowledge is HM Bismark then they would not get off his back until they are thrown - since they know time is important and would want to get as much damage in as possible. Even if they were able to get it down in one go and avoid this, they would get hit by it at the end when you go on the 2nd time.

False. Did it blind with 7 others, not a single one of us knew it. We mostly knew what was going on from the previous fight and the dps learned the hard way about the debuffs, myself included. Healers didnt even know why we were taking so much damage until i noticed the reflected message on my screen similar to Levi EX. I was a prime example of the 3 stack debuff that killed me and a drg. I dont know how many HMs you've done but most of the ones ive been in run off his back once he shudders just out of fear, so did the same. Wipes did happen and we learned from them. I feel like he is one shotable blind but that could be contested (That party would need to be very very good at noticing things as soon as they happen and probably have voice chat...maybe not the voice chat. In any case they would need to be very on point). He definitely however is beatable with a party going in blind/with Hm knowledge. Ravana I can say took us a lot longer doing it mostly blind. Last phase we did have someone explain what was screwing us up as she did it before us. Even those who know the fight at one point went in blind. And those who looked up guides? Guess how them guides came to be.

If we mean one shotting it blind, I doubt many could do it. If we mean after 2+ tries of going at it blind, then yes, monkeys can eventually figure out what's going on.
