Cotrangl (Lord of the celestial ocean) is one of the two bosses of the Azure Rainforest, and will be battled on B15F. Kupala summons it in order to stop the explorers from advancing further into the labyrinth.

Contrary to the previous bosses, Cotrangl doesn't summon allies, and fights alone.

Strategy Edit

Cotrangl is pretty tough. Compared to the previous bosses, who where more defensively oriented, Contrangl is a offensive boss. This means that its attacks hit very hard.

Its main attack, Tackle, hits a single character for a ton of damage, often close to 200 HP. This can be reduced by Immunize and Protect, but even so, the damage is considerable. Blizzard hits very hard too, often dealing damage to a whole row. Flood is the most dangerous one. Although weaker than the previous ones, it hits the whole party, and worse yet, it can use this attack many turns in a row.

Although it may not sound that intimidating, keep in mind that Defender won't reduce elemental attacks damage, meaning it is only effective against Tackle, and even though Immunize is pretty useful, the protection wont be enough to allow you to survive a lot of hits. Cotrangl has lots of HP too, meaning useless you have a good offensive party, this fight can extend itself for quite a few turns, with is pretty bad. So, for a change, try not to be overly defensive against this boss, but don't forget to keep the defenses up, so you can withstand a little longer.

On addition of following strategies, you can use Blaze Oils, to increase damage dealt. Cotrangl is weak against fire, so using Flame with a alchemist is the best way to deal damage. Blazer is the best choice for your landsknecht, since Cotrangl has no allies, meaning Allslash is ineffective. Survivalists are effective on this fight, since this boss has low defenses. Boosted Apollon and Multihit can hit very hard when used along Blaze Oils. If you trained one, ronins are very helpful too, although its risky to use one, due to their low defenses. Midareba and Orochi are very powerful, and will deal a great amount of damage. A good medic is mandatory for this boss. Immunize is a must in order to reduce the damage dealt, if boosted, the damage will be ridiculous. Salve and Salve II are important too, due to the multi damaging skills. Revive is recommended too, in case it gets you off guard, but not mandatory. Caduceus can help dealing damage, but its recommended to focus on healing instead. Although helpful, a protector wont be necessary for this battle, unless you will be using Anticold, to block the boss skills, but its TP consuption is very high at this point, so doing so isn't recommended. Defender will only protect against Tackle, so it isn't mandatory for this fight, Despite that, Smite can deal some nice damage, and is pretty helpful. Troubadours, as always, are a very good choice for support. Ymir, along with Immunize, can reduce the ice skill's damage to nearly nothing, leaving only Tackle to worry about. You can also use the support skills to help at surviving or dealing damage, depending on your play style. Hexers arent very useful on this battle. While they can bind the boss and cast both Sapping and Frailty to weaken it, they wont be dealing much damage to it, useless they use revenge, with is very dangerous since the boss use flood very frequently. Although not very helpful either, dark hunters can use Bait to lure the boss into using Tackle into a stronger character, and can bind too. Recommended parts to bind are legs (blocks Tackle) and head (blocks Flood and Blizzard), although this boss is resistant against binds.

Corotrangul returns in Etrian Odyssey Untold, still serving as the second of the two stratum bosses of the third stratum Azure Rainforest at B15F, as well as being the first stratum boss to not rely on minions.

It relies heavily on Ice attacks, so equipping your party with gear that increases Ice resistance or having a Protector with Ice Wall at least level 5 will make the fight much more manageable. A Medic to remove the Sleep caused by Flood and the binds caused by Coiling Tail is also recommended.

It is weak to Fire moves, but can use Aqua Veil to temporarily remove this weakness. If removing the buff is not possible (ie. Troubadour's Eerie Chorus), physical attacks are recommended.

Skills Edit

  • Aqua Veil (Uses Head): Raises Fire resistance for 3 turns.
  • Coiling Tail (Uses Legs): Binds head, arms and legs of a single target.
  • Flood (Uses Arms): Heavy ice damage to random party members. Will not hit same target more than once. Can inflict sleep. Hits 3-5 times. Tends to not be used before 50% hp is lost. (unconfirmed)
  • Freeze Aura (Uses Head): Increases physical and elemental attack for three turns.
  • Ice Breath (Uses Head): Heavy ice damage to whole party.
  • Tackle (Uses Legs): Melee bash attack that pierces across lines, dealing heavy damage.

Drops Edit

  • Huge Fin (Worth: 2390 en)
  • Venom Spine (Worth: 11540 en)

Conditional Drop Edit

  • In order to acquire its conditional drop, Venom Spine, you need to defeat it with poison damage. Killing it while poisoned without using the posion damage itself will not yield the drop. The Venom Spine unlocks the Arc Drawer, the strongest bow in the game.

King Grimoire: Edit

  • Sea Grimoire: A grimoire stone born in battle with Corotrangul. A stone containing special skills.
    • Abyssal Prayer: (TP Cost: 30) Lowers the TP cost for all allies this turn.
