Instant kill in trial of the sekhamas

I was in to the last (4th) trial, about half way through, I was given an option to take 188 damage for restored honer but instead it killed me and sent me to the start of the entire trial. This is frankly very frustrating. a waste of 2 hours of my time for nothing. Please look into this bug as it has not only caused a great amount of discontent personally but I am sure I wont be doing this again as will others. bit pants tbh.
