Best Immortal Pairing for Frederick I
In order to gain best combat efficiency and performance, we recommend pairing Frederick I with these fire immortals below. One of the main advantage that Frederick I has is the ability to restore health and deal damage. With these passive skills, especially Life Link, he will be able to provide a sustained amount of damage to multiple enemy targets while balancing your front-row.
William I

Easily one of the best fire immortals to pair with is William I. His active skill gives +20% critical rate chance bonus that makes it quite common to land critical hits. Frederick I’s active skill is based on amount of damage dealt to the enemy targets. If he lands a critical hit, then he will be able to convert even more of damage to health.
Which is why William I and Frederic I makes the perfect pairing to have on the front-row. Both are physical attackers, but Frederick I will make an excellent tank unit while William I provides much needed damage booster through dealing critical hits.
Cyrus the Great

If you plan to have William I on the same team with Frederick I, then you will want to have Cyrus the Great. He can lower enemy targets’ resilience rate, which makes it easier to inflict damage. In addition to that, he grants a stun chance whenever the enemy targets are critically hit.
This means every time Frederick hits enemy targets with his active skill and lands a critical hit, he will be able to stun them for a few seconds. Stunned enemies can’t do anything, not even perform basic attacks and that really helps give a breathing room for Frederick I to restore his health. Absolutely a formidable pairing.
Empress Wu

One of the main advantage that Empress Wu has to offer is the ability to deal magical damage. If you need a spellcaster that can take advantage of your enemy’s weak spots, Empress Wu is an amazing magical immortal that does a lot of damage with her active skill. While she doesn’t benefit Frederick I directly, her high damage output will be able to chip off tough enemy units to lower incoming damage.
Combined with William I’s critical rate chance bonus, Empress Wu will be able to make a quick work out of enemy troops with her powerful magic active skill. A high magical damage output is definitely a plus for the fire team.
Ashoka

If you want to take advantage of increased damage output, Ashoka is the perfect fire immortal to go with Frederick I and the team. He can fire a powerful active skill that does a massive amount of damage to all enemy targets. Plus there’s a chance his active skill will deal double damage.
In addition to that, the critical rate chance bonus will further increase his chance to deal significant more damage. Which makes him one of the most powerful ranged immortals in the game. If you are looking to make a quick work out of your enemies, you may want to consider getting Ashoka on the team.
