Yin Combat Focus (3.5e Feat)
From D&D Wiki
 Yin Combat Focus [Combat Form]
Your Combat Focus training enhanced your defensive Ki powers.
If you have three or more Combat Focus feats, these bonuses increase to +2.
A fighter may select Yin Combat Focus as one of his fighter bonus feats. A monk may select this feat as one of his bonus feats at first, second or sixth level without fulfilling the prerequisites, but he also needs the Combat Focus feat to benefit from it.
