Those of an evil disposition who use these creatures for their foul purposes are unlikely to read these rules yet alone obey them. They deserve everything they’ve got coming. The Queen and her Council hope they get a decent ringside seat to watch poetic justice being handed out. The Queen is always keen to pick up hints on how to improve her own magical skills.
The humans have a phrase “survival of the fittest”. Not only is that true in the magical realm, it is equally valid to say the fastest will survive. So therefore all magical beings in the direct service of the Queen and her Council will practice firing spells at targets, drawing wands (or staffs) at speed and be ready at any time to demonstrate that practice has been carried out.
The Queen and her Council are experienced enough to be able to tell when “revision” of this nature has been carried out. Also all magical beings will be responsible to their species’ leader and be able to demonstate regular practice is being carried out to them too.
