We just spent over 3 hours and over 10 phases because of how insanely rigid the stun/DPS mechanic is. It’s a little buggy in general with the bell sending people out of nowhere. We just lost because the bell teleported us out of nowhere. One guy was off the side when we appeared and just fell to his death. As for actual DPS, It’s either do hardly any damage, or she teleports you even if you stun when she’s near the bell. It happened every time for us. There’s not enough time when she gets within the bell circle to make it work properly. It happened every…..single….time…. We had to choose to to do next to no damage each phase or do no damage because she teleported is anyway.
