How Do Duel Skills Work?

This is an article on Duel Skills in Fire Emblem Heroes (FEH). To know more about Duel Skills, the units that can inherit them, and how they raise your score in the Arena, read on!

What Are Duel Skills?

Skills to Increase Arena Scoring

Duel Skills are mainly used to increase your score in the Arena.

If a Duel Skill like B Duel Flying 4 is equipped to a unit with BST less than 180 without any modifications or merges, it will treat the unit's BST as 180.

This is important as it places the unit at the same BST calculation as Armor units like Winter Felix and Halloween Hector, even if they are Infantry or Flying.

You can use Duel Skills to boost your favorite unit's scoring.

In the example above, we used a unit with a BST of 158. In the first row, they were given a Duel Skill and below is their score without it equipped.

Duel Skills are very useful for units that have weaker Def or Res, such as those with rnaged weapons, as they will benefit more from the boosts provided.

Using the Bonus Unit is more important!

However, even if you give someone a Duel Skill, you need to remember that it's more important to defeat at least 1 enemy in the Arena with the bonus unit!

Defeating an enemy with the bonus unit will add +12 to your score, so even if you don't have a Duel Skill, you can still go up the tiers.

Duel Skills are only for 5★ units

Please note that Duel Skills are only available for 5★ units and the maximum unlocked skill can only be inherited to 5★ units.

Recommended Units to Inherit Duel Skills

Powerful 5★ Units

It's highly recommended that you give any Duel Skills to a unit you frequently use in Arena.

As Duel Skills don't count merges, you can +10 your unit and give them the skill to boost their score further.

Units That Are Easy to Unlock Potential

Duel Skills are also very useful for units that come in 3★ or 4★, as they are easier to unlock potential and merge.

Units such as Nino and Caeda are good candidates as they are easily obtainable and merged, and are good in Arena.

Summary

In the Arena where a point can make all the difference, Duel Skills can give your units the edge they need for you to be able to go up in the tiers.

If you want to get a high score and reach the highest tier, we recommend inheriting a Duel Skill to one of your units.

However, if you don't have Duel Skills to give, it will help a lot if you defeat enemies with the bonus unit for the week and merging them up!
