|A Wingling Barbarian stands his ground.|
How they are different from Halflings: Winglings are roughly a foot tall. They have translucent wings reminiscent of dragonflies attached to their back. What their weapons lack in bulk and power they make up for in the ability to pierce weak points in armor, wedge into soft underbellies, and slice open squishy exposed bits.
Did you say wings?: Winglings were built to flit from branch to branch, not hover safely over a battlefield and rain down arrows. Though they can fly, they still must engage targets like every other character. The winglings also punctuate their speech with the buzzing of their wings. The louder the buzz, the bigger the curseword.
Shouldn't there be additional rules because of their size? I've never met a set of scaling rules that I liked. Any abuse will be policed by the fact that winglings have antlike strength for their size and the adjustment of DCs when their size comes into play in the fiction. Hiding amongst the junk in a curio shop? Lower DC. Lifting the barbarian's broadsword as a weapon? Higher DC, and hope you don't roll a 1.
Cultural information: While not as pronounced as the split between the elves, Wingling culture does differ between those who live in the forests and those who live in the cities. Treetop winglings think their city cousins are stuck up sell-outs. They make their way living (and stealing) off the land. Tower winglings wonder why their backwater relatives still live in mud and eat bark. Civilized winglings are in demand as servants and spies.
The others think: Elves treat winglings like the pesky little brother they never wanted. Gnomes get along with winglings as fellow travelers in a Tall Man's world. Half-orcs must resist their natural tendency to swat them down.
