Magical winged serpents that can shrink to the size of a mouse or swell to the size of house in an instant the Occamy is fascinating creature to say the least. As with most of the magical beast from the world of Harry Potter it isn’t too dangerous unless provoked, however there is a great deal of fun here for GM’s an players alike. As the Occamy shrinks and grows think about what sort of environment you’ve placed it into. If it is hiding out in a Muggle department store the roof might start caving in as the serpent crushes support beams for example. Occamy are also fiercely protective of their eggs making them more likely to attack anyone coming near their nests.
