Spells are used by merpeople to do things their natural powers don't allow them to do. Spells usually need ingredients.
A northern recipe with few ingredients required but a very complicated and delicate technique of cooking. Add foul-smelling oysters and Arctic sea lavender into a bowl, then cool the water to the temperature of the Beaufort Sea at the end of December, which will cause the flavors to transfer. The process has to be gradual and cannot be rushed, otherwise the flowers will freeze and the shells will break. Once the sand on a small hourglass runs out, immediately add a dash of dried plankton of Baltic Sea to stop the transference. Its also can be used to stop the Eastern spell of Knowledge Transference.
Fifty Moons Potion
This potion magnifies the effect of the Full Moon to fifty. The potion is required to be used on merpeople, with the help of Hydrokinesis, in the Moon Pool during the Full Moon. The merperson which the potion is used on supposedly loses their powers forever. This potion is green in the appearance. This spell possibly stimulates the effect of the special planetary alignment we saw in H2O, that only occurs naturally every fifty years and removes one's powers forever.

Turn the Tide
Turn the Tide is an Eastern pod spell used to turn magic back on itself. It is a form of Eastern mermaid self-defense. It is a very difficult spell to learn and Eastern mermaids are taught this spell when they are hatchlings. No Southern mermaid has mastered the spell, but a couple of them have tried.

Wish Granting gives merpeople the ability to grant wishes. After the ingredients are mixed with three powers, the solution needs to be smeared on a merpeople's face who is in a mer-form. Then a wish can be made by others: either out loud, or only thinking of it (it may take a while for the wish to work).
