Komainu Rider

Models with this rule must always accept challenges and re-roll all failed Psychology tests. In addition, they treat friendly units without this rule as Expendable.

Whenever a unit comprised wholly of models with this rule is required to take a Break Test, they may choose to do so using 3D6, discarding the highest dice. However, if this test is failed, you must remove the entire unit as a casualty. The enemy then cannot pursue or overrun, but may reform as normal.
