Fortitude Battle: Target your unbowed Berserker: Bow a target enemy unit with lower total Force than your Berserker's base Force. Until the turn ends, negate all current and new Force penalties on your Berserker from actions.
Disarm Battle: Target your Monk: Target an enemy Personality. If he has no Weapons, reduce his force to 0. If he has any Weapons, destroy one of them. You may attach a Weapon from your hand or discard pile to your Monk.
Low Stance Battle: Target your unbowed Samurai Personality: Target an enemy Personality. After this Combat Segment ends, reduce his Force to 0.
The question is: If I play disarm on a berseker and his force is now 0 can he perform fortitude and Bow me? e.g. Kagura is 7 base force and I played disarm with Taro we plays fortitude bows me and negates the penalty. Then I play Low stance with kuroki but on the resolution he is still 7 since fortitude works like shamefull injury also. Is that correct?

If I play disarm on a berseker and his force is now 0 can he perform fortitude and Bow me? e.g. Kagura is 7 base force and I played disarm with Taro we plays fortitude bows me and negates the penalty. Yes, since Fortitude checks the Berserker's base force.
Then I play Low stance with kuroki but on the resolution he is still 7 since fortitude works like shamefull injury also. Is that correct? Yes. Fortitude negates the penalty from Low Stance.
