This mod will not work if:
1. Your captain and/or friend captain is despaired (so bring despair reducer or swap ability that can remove despair - only work once)
2. Your captain and/or friend captain is blown away (so use legends like franky, osoba mask or capone)
3. When enemy has barrier and you can't kill it one turn (turn off your one hit mode and stall until barrier is gone, or have someone to take out barrier, or someone who can bypass barrier, or make sure to kill in one turn.
4. For swap mechanics that can remove despair like inu/neko and lace, you can only swap once for each captain/helper when you are despaired. If you will get despaired again, don't use the swap mechanic and have some special to remove it.
5. Not sure for this one, but if the enemy had blue defense up, remove it first before killing it unless you are sure you can beat the enemy with it. There are some contents that has high blue defense up.
