Mighty Oak is the first boss of Epic Battle Fantasy 4, and a unique Limit Break for Anna.
As a boss
Mighty Oak is not an antagonist. He only fights the party to test their worth, joining as Anna's Limit Break once they defeat him.
As the first boss, Mighty Oak should cause no significant problems to the party. It is recommended to have the Protect ability to reduce his damage, a dispelling ability (since he may buff himself), and Fire magic, which he is weak to.
As a summon
Mighty Oak attacks foes, dealing high physical and earth damage to all foes and hitting 9 times. As a physical attack skill, it may be wise to use the Iron Tooth to increase its potential damage. You can also combo this skill with Debilitate and Beer to maximise its power.
Hitting 9 times, accuracy should not pose a problem.
Take note that this skill deals 50% earth elemental damage, so its overall power will increase if targets have a weakness to earth.
This can also work both ways however, as foes with a resistance to earth will take less damage. It may be wise to give Power Blast to Anna to make up for this shortcoming.
Trivia
- The Mighty Oak may be inspired by the "Great Deku Trees" from the Legend of Zelda series.
