Possible bug, either way be careful!

I was in the next to last room in trial 3 at the Trial of Sekhemas and i had exactly 91 honour left (lol). I decided to switch my weapon set to my stronger/more offense set, since 91 honour would one shot me at the boss regardless, and when i switched i dropped to 0 honour, but could still move. I went to the shrine to restore 500 honor, and instead, it killed me. Mo idea if that's a bug or what, but i was not happy. I expected it to restore honour, but apparently if you do what i did, it just kills you instead.
