Narnian Dryad Race-Class

In my Skype campaign, though we use Swords and Wizardry as the foundation we build on, we don't use race-as-class except for "magical" beings. So far, magical PC races are gnomes, brownies and dryads. This is our dryad race-class. It's based more on the dryads in C.S. Lewis' Chronicles of Narnia than on the dryads of Greek myth, since, well, everyone in the campaign is a Narnia fan. No Dryads, PC or NPC, have appeared in our campaign yet, but we drew this up after one of my players requested it.

Dryads are able to cast any Druid spells specifically approved by the Referee or from sources approved by the Referee, using the alternate magic system found in Green Devil Face #4. (So far, approved sources are OSRIC and Ancient Vaults and Eldritch Secrets.)

Each Dryad has a tree; in fact, each Dryad is the spirit of a tree. The Dryad dies when the Dryad's tree dies (and vice versa). It is physically impossible for the Dryad to travel more than a day's journey away from its tree. The Dryad may also animate its tree as a Treant of three more hit dice than the Dryad's level. While animating its tree, the Dryad cannot use magic.

Dryads do not normally have any use for treasure. Unless the Dryad has some pre-set, unique reason to desire treasure, Dryads do not share in any loot gained during adventuring.
