Pretty silly mechanic that if one of your party dies during a boss fight, everyone has to fail, as the player who dies, gets locked out and does not get credit for the boss fight. This needs to change.

vivid quest
mild moss
100% agreed. stupid feature. be there for 90% of the fight, die to a 1 hit combo and have to redo the whole thing
