  • Corotrangul always opens with Ice Breath.
  • Corotrangul's chance to use Coiling Tail is increased slightly if no party members have binds.
  • Corotrangul will never use Coiling Tail twice in a row. It has to use Flood, Ice Breath, Tackle, or a normal Attack before it can use Coiling Tail again.

  • Phase 4: Lasts from 50% HP to 36% HP. Corotrangul opens this phase with Flood. After that, Corotrangul will use Flood randomly. Its chance is increased based on how few turns are left on its 5 turn cooldown. Besides that, it uses Ice Breath and Tackle.
  • Phase 5: Lasts from 35% HP until death. Corotrangul will open this phase with Aqua Veil, and will refresh it on cooldown. In addition, Freeze Aura will no longer be used in this phase. Outside of these, this phase has similar priorities to Phase 3.

Corotrangul means business, and going into it unprepared will get you killed quickly. He has three hard-hitting attacks, two of which are elemental, all of which are probably likely to one-shot all but the sturdiest party members--or, in the case of the elemental attacks, likely to severely injure or one-shot anyone that doesn't have good TEC.

You're also gonna need to bring either attack debuffs or Metopons to Corotrangul, because letting it get off Freeze Aura and keep its buff is going to get you killed eventually. It's damn near impossible to keep up with Corotrangul's damage when it's dealing an extra 50% on top of its already-high baseline.

Oh, and for one last Fun Thing, Corotrangul can also nullify its fire weakness. Again, you're going to want Metopons to dispel it, or Flame Fantasia to prevent it from being applied in the first place.


Got all that? Good. Let's go over the choices we have.


Judith: Judith has War Cry, but it's a bit of a liability in this fight, especially for her personally, since she already has really bad TEC and is going to take a large amount of damage from Ice Breath and Flood.

Elowen: Elowen will take a lot of damage from Ice Breath on Flood, but on the other hand, she has Efficiency on her side, along with her innate quickness. She can quickly negate Coiling Tail by just having some Theriaca As in stock, for instance.

Vince: Vince is a massive boon for Corotrangul, solely because of Ice Wall. It completely shuts down Ice Breath and Flood, which are Corotrangul's most dangerous attacks. Tackle will still hurt, but it's far easier to deal with than Flood or Ice Breath.

Sigrid: Disables are always welcome when fighting bosses, and Sigrid's one source of them. Both her sword ailments and whip bind are useful here--which I go with will depend on the composition of the rest of the party. For example, head and arm binds are less valuable when Vince is around to stop Ice Breath and Flood.

Thierry: CPR is even more useful than usual, due to Flood and Tackle being likely one-shots if they go off. Other than that, as long as Thierry himself isn't the target of Coiling Tail and doesn't get afflicted with the sleep from Flood, he can purge both of those...if the other party members aren't dead, that is.

Katya: Katya deals fire damage. Corotrangul is weak to fire damage. Katya also has high TEC, meaning she won't take as much damage from Ice Breath and Flood, if they're not completely mitigated to begin with.

Emmett: Emmett has the ability to purge buffs, buff our party's attack, and provide ice resistance, in the form of Frost Fantasia, if I have no better options for ice damage mitigation.

Momoe: Momoe deals heavy, heavy physical damage. She basically needs Vince if she wants to stay alive, though.

Quixote: Disables are never a bad thing to have, and Quixote brings them to the table in spades. Leg binds are especially useful if Vince is around, since they render Corotrangul basically helpless.

Afon: Bloody Offense is never a bad thing to have, and Afon can contribute elemental damage. Now that she's starting to get a few levels, her real power (ie. Delayed/Cross Charge, with Spear Assist inbetween) is starting to become very viable.

Ladette: Elemental damage is good for Corotrangul, and Ladette has it in spades. She can also function as an emergency bind source, if I'm really desperate.
