– Official description
Previous Cor guides:
Cor, the Immortal
He received this nickname due to his ability to escape from even the most impossible situations. Even though he hates being called The Immortal, it doesn’t stop him from performing his royal duties in protecting the King and his family.
Cor Hero Skills
Cor is a good all-around combat hero since he boosts just about every troop you use in battle. There is one skill that increases Kingsglaive Ignis’ Order of Hero boosts, but since this is a Hero Skill, Cor has to be your active hero for that boost to be activated.
- All skills require Hero Level 202 to unlock.

Cor Mirror Hero
As with all of the most recently released heroes, Cor has new Mirror Hero stats to keep up with the current Royal Dark boosts needed. Don’t forget that there are some researches in the University’s Mirror Hero section that you need to complete to get more boosts from Cor’s Mirror Hero.
- All Mercenary Royal Dark
- Attack (up to 20M% combined)
- HP (up to 10M% combined)
- Armor (up to 30M% combined)
- Royal Dark City Defense
- Attack (up to 20M% combined)
- HP (up to 10M% combined)
- Armor (up to 30M% combined)
Although, these stats are not quite up to current standards, so other Mirror Heroes should perform significantly better than this one.
Compare Cor and Gilgamesh
Even though Cor boosts just about every troop with stats that are just about up to par, he doesn’t match the Debuffs included in Gilgamesh’s skills. Most of the troop boosts for Cor are a tad smaller than Gilgamesh, but his Mastery skills will still be useful to boost the troops when any other hero is active.
Cor boosts Fort stats while Gilgamesh boosts Vaults.
Cor Dark Hero Medals Chart
Since the most recent Dark Hero levels have used the same medal requirements, here is the chart updated for Cor and Gilgamesh. If it changes as Cor is leveled up, please let us know on Line, Discord, or in the comments!

Summary
Leveling up Cor will be good to include his Mastery skills in combat, or in addition to his Hero Skills if he is your active hero. Even though he doesn’t offer any troop-specific focuses, his general combat abilities are on par with previous releases and will offer your empire some strength in battle.
