Courage

Reduce damage by 60%. Whenever an ally deals damage to an enemy, if that enemy is above 50% HP, grant Guard Shield and Sacrifice for 1 turn to that ally. Whenever another ally dies, gain Perfect Revenge and Echo for 3 turns. Remove Fear, Exhaust, Stop and Seal from each ally after every action. For each ally affected in this way, permanently increase their ATK, MAGIC, DEF and MR by 200% for 1 turn and have them deal a hit of true damage to a random enemy.
