Druids are spellcasters that study the magic realm of Druidry. They specialize in "nature" type spells, like lightning bolts, whirlwinds, tidal waves, etc. They also control life of the wild, like plants and animals. In fact, they have a special skill to call forth creatures in nature to help them in emergencies. They even have the ability to train and handle animals without the use of magic at all.
