The Kuni themselves are not really militant - not by Crab standards. They won't be going into battle swinging weapons unless it's necessary. There are plenty of Crab warriors plenty good at swinging weapons. In a Clan like the Crab, everyone focuses on what they are good at. Though I would love a path to allow them to give a better effect in battle. Maybe something like...
Path: Earth Protector [Shugenja]
Technique Rank: 3
Replaces: Kuni Shugenja 3
Requirements: Earth 4
Technique: We Are the Wall - While the Hida take the role of the shock troops on the front line, the Kuni use the power of the Kami to make sure the Hida will outlast their enemies. You may expend an Earth spell slot as a Simple actions to give someone a reduction rating equal to your Earth Ring for the next hour. You can only apply this blessing to as many people as your Shugenja Rank (the oldest extra blessings are lost).
It boosts the Hida, but also can help anyone in a combat situation.
