They have devoted their lives to protect the nature and destroy those who wish to pollute the nature's beauty.
Druids have the unique ability to take up the form of a wild animal. Their special bonds with nature also let them treat wild animals as allies, and
Druids are predominantly Wood Elves, but peoples of other races can be druids too. Most of the non-elf druids are fostered by Wood Elves.
In the original forum-based RPG, being a Druid requires an Intelligence of 12 and a Wisdom of 14.
Being a magician grants the character basic knowledge of tracking, advanced knowledge of the Ancient Language, as well as the unique feat of being able to sense magical energies around himself/herself, and shapeshifting.
In the video game adaptations of the FRPG, Druids are similar to Magicians in the sense that they are limited. They cannot wear any armour and their selection of weapons is limited to staffs and clubs. In the 2012 game, they have even lesser hitpoints than Magicians.
However, to compensate for that, they have very high amount of spellpoints, and combine the advantages of Magicians and Clerics - being able to learn spells from scrolls, and gaining spells at levelups.
