Because shut up, Halflings are cool as hell.
Thanks to DrPete for suggesting changes that I have subsequently made to it.
Playing a Halfling
At first level any human, non-Arcane character may choose to instead play a Halfling, a tiny relative of Dwarves and Humans. In doing so they must sacrifice two proficiency slots to purchase the following proficiency.
Halfling: The character is a halfling, a tiny relative of humans and dwarves. His lifespan is half again as long as members of his race, and he enjoys a +2 bonus to AC against creatures of man size or larger. Additionally, halflings, like Dwarves, are Hardy People so the target value for their saves vs. Blast/Breath are reduced by 3, and the target values of all other saves are reduced by 4. However, halflings are very small in size and are subject to the following additional restrictions:
The maximum weight a halfling can carry is equal to 15 stone, plus his strength adjustment.
A halfling cannnot use longbows, arbalests, or melee weapons that require two hands to use, and never uses the increased damage value for using battle axes, flails, maces, warhammers, spears, or swords two-handed.
A Halfling does not automatically gain the Adventuring proficiency.
