Backfire
This tinker has the possibility of a backfire, resulting in the engineer being launched straight up into the air. In some cases, a slow-fall buff is applied to reduce the risk of death. In others, the distance launched is unnoticeable, appearing as if they simply failed to activate. In all cases, the cooldown period is started.
