Armstrong (The After Years)

Armstrong is the boss that is encountered at the end of the Lunarian's second Challenge Dungeon in Final Fantasy IV: The After Years.

Strategy
Armstrong's attack power rises whenever it is hit with magic, and there is no limit to how high it can go. Because Golbez's and Fusoya's HP can exceed anymore than 2900+ in their tale, it is unadvisable to cast magic on Armstrong. If Fusoya casts Haste and Berserk on Golbez, he should be able to defeat Armstrong while Fusoya heals both of themselves. The battle is even easier if Golbez has either the Enhance Sword or Defender. Despite focusing on its strength, Armstrong sometimes uses magic, but it is not too much of a threat. Sometimes it will self-destruct on both Golbez and Fusoya as it nears death, if they don't kill it first.
