Steps:
1. Attack a monster with a spell on a job that is capable of defeating the monster in a single blow.
1a. E.g. RDM casts verthunder on a level 59 Earth Sprite in Hinterlands and defeats the monster in one strike.
2. When/as the cast finishes, quickly swap to BLU.
3. BLU will recieve all of the exp despite not having been the job that dealt the killing blow.
4. Chain exp functions as normal, consecutive kills using this method will result in more exp earned by BLU assuming that one follows the prior steps.
5. Using weaponskills, instant actions, or off-global cooldowns will not work, as it will not be possible to switch jobs.
