In some battles, the enemy have a advantage like a first strike or a flank attack. You can avoid it using the timeshift to don't let the enemy catch you first.
You can turn around it by using the bluff or addle skill, flank and rear attacks, or hitting the timming minigame to do a workgroup.
- Let's not forget that the battlefield affects your starting morale as well.
- As well, certain characters will start with lower morale than others. Check the Last Remnant wiki for details as to who will likely have higher morale to start. For example, having Rhagoh or Kate will start you with lower morale than if you have Darien.
