Dream offered a good summary of the halfling ORDER OF THE HIN FIST (aka the Hin Disciples) earlier in this thread, so I wanted to highlight their unarmed combat style, which was called the Way of the Open Hand, also known as the Way of the Empty Hand or the "kung fu" of "Shou-Ling" priests of the Shou Lung region. The fighting style of the Hin Fist was actually only one of a family of unarmed techniques by that same name (Kung Fu/Way of the Open Hand) in Forgotten Realms.
As described in D&D, the Hin Fist style used a foe's greater size and strength against them offensively and defensively. The unarmed style explicitly doesn't involve grappling, submission holds, or deflection of attacks. Rather, its techniques are intended to turn an attacker’s force to one’s own advantage rather than to oppose it directly. The style uses speed and tumbling to evade and launch attacks, getting under an attacker's guard to use the attacker as defensive cover, and tripping an attacker so that allies get an advantage against the now prone target.
The supernatural abilities ascribed to the Way of the Open Hand includes the act of meditation producing a Sanctuary spell-like ability (an "aura of peace").
Monks of the Hin Fist could freely multiclass with Paladin, Rogue, and Fighter. Members were exclusively halflings, gnomes, and dwarves (and, in Luiren, only halflings). They'd fit perfectly at Brog and Bendir.
How to build - Discipline of Body monk with possible multiclass to Paladin, Rogue, or Fighter. Grab Brawler, Pugilist, Ki Sprint, Ki Barrier, Drunken Fist, and Armor Skin as a Body path Practitioner, and -- if possible -- Open Hand of Deliverance and other feats from the Spiritual Path. Train in Discipline, detection, and Tumble. It is a pity that halflings and others of small stature would have a harder time tripping/knocking down others though otherwise I'd recommend the Knockdown and Improved Knockdown feats.
