I rolled up a Ranger as my first character when I bought the Advanced Dungeons & Dragons (AD&D) player's handbook back in 1984. I was a big fan of Ralph Bakshi's animated Lord of the Rings film and wanted a character like Strider. These days I've come back to preferring the rules Basic & Expert (B/X) Dungeons and Dragons, but there are some features in AD&D I'd like to use, including the Ranger. It's interesting that when you strip out the more verbose language from AD&D the actual rules required for a Ranger are a lot less than you'd think and fit quite nicely into the format for B/X.
In later editions they made the Ranger more of an Archer, or a duel sword wielding character based on the Drizzt novels. I prefer the original concept though, which was closer to Tolkien's Rangers. Warriors who travel the wilderness hunting bands of marauding humanoids in order to keep them from crossing over into their home kingdoms. The extra hit dice at first level and bonus to damage for melee combat against humanoids also make them a great choice for small (or solo) 1st level adventures.
Dryads are female tree spirts who live in woodlands or dense forest. When young, many leave the forest to travel the world before settling down and living within their tree. While adventuring Dryads look like children, but they are really spirits in human form and more powerful than they at first appear.
This is a new character class for the original Basic & Expert (B/X) Dungeons and Dragons game. Dryads have some special abilities that a magic-user does not, but they are more limited in their selection of spells and like the demi-human classes have a maximum level they can attain that's lower than their human companions.
Spending some time outside this weekend working in the garden was the inspiration for this new class. Adult Dryads must stay near their trees, but what about their daughters? Perhaps like seeds they can travel on the winds for a while before putting down roots.
