I am going to break my no posting with a current rule to address this.
The first time it fired on you (and you were the first person it fired like that on) I was stoked, thought it was really neat. I have fought many many rounds and it has gone off doing different things but not once did it do that.

The second time it fired, and in the first round or two, I felt really bad. After that I avoided pressing any confrontation with you because I didn't want that to happen again until it got looked at.

One of two things happened from what I can tell. There is an issue with the Azure race (perhaps a specific save, maybe their vulnerability to negative). Or there is something that you were affected with that the druid hit you with that was letting it fire and you miss your saving throw.

Sorry that you gave up because of that, your character was fun to fight against.
