To develop Kongjin Fa, if I understand correctly, you need:
<span class="s2">• </span>Wushu (more ranks than Kuo Sho)
<span class="s2">• </span>Weapon focus in Wushu
<span class="s2">• </span>Kuo Sho MA Style (more rank than Kongjin Fa)
<span class="s2">• </span>Lore: Kuo Sho (if you want to buy moves or special abilities)
<span class="s2">• </span>Kongjin Fa MA style
<span class="s2">• </span>Lore: Kongjin Fa (if you want to buy moves or special abilities)
If you disregard the one-time cost for Weapon focus, that means you are required to pay 10 ranks in Wushu and KuoSho before buying 10 ranks in Kongjin Fa. Probably you will have Wushu and Kuo Sho as favored skills but even so, the price in CP will be hefty (50 CP if you have both Kuo Shoand Wushu as favored, 70 CP with only Wushu as favored... and this is without buying any rank in Lores, Combat moves or special abilities).
The cost is going to explode for ranks above 10. Even with all skills marked as favored, it will cost 15 CP just to upgrade from 10 to 11 ranks in Kongjin Fa.
Is this how it is supposed to work? I think it may be a little bit expensive.
