Elementals
Elementals are creatures which derive their power from a single element of nature, representing the attributes of that specific element. They may be summoned by those who possess high enough skill level in the Elementalism skill, which is shared by the Magi and Sylvan classes. There are four known elementals, each representing a different element. They are learned in the corresponding order:
1. Water -the water weird, which allows the person it is following to walk on water.
2. Earth -the sandling, which sequesters the caster underground, protecting him.
3. Air -the aerial, which carries the caster into the sky, granting them the ability to fly.
4. Fire -the efreeti, which attacks the caster's enemies, setting them on fire.
Of the elementals, the waterweird and the efreeti are denizen creatures, while the sandling and the aerial are not. There is no elemental for the Priest class's Spirit element.
