signature move changed?

When my theatric first used signature move, it was a stun, but then the next five times he used it as a disarm move. Does anyone know why it changed?

sometimes you do a different sig move to your main one. going by what you say, disarm is your main move

I see. I thought the sig move was set in stone, thanks

For some it's set in stone, for others they do a variety all the time. I've had both cases.
