Clear Steps

Welcome to a bit of RNG. We cannot see the location of the Boss immediately, and will need to find a hidden Ouroboros in order to do so., Ouroboros is hidden behind one of the three radars on the map. Which Radar is chosen at random, and can make this map rather frustrating. With a bit of luck, she will be behind the Radar on the right. If she is not, it is recommended to simply reset. The fights on this map can pile up Damage quickly, making it better on one's sanity to simply reset and try again. 

We will be getting the secret objective simply by playing the map, which is nice. 

The Boss can be a threatening enemy and has 2 distinct phases. 

1st Phase: The Boss will periodically spawn club throwing enemies with HP shields. These enemies hit relatively hard, and can stun your tanks, preventing them form using defensive skills. When these enemies are spawned, quickly wiggle your ARs to force them to retarget the new enemies, either clearing them up so the DPS can focus on the Boss again, or a rifle can fire on the Boss. This phase lasts until the boss is reduced to 50% HP. Try to avoid having her spawn her trash when the phases shift. 

2nd phase: Boss with periodically trigger AoE blasts that stun your 2 highest DPS Echelon members, or damage Dolls in the front two columns. You can creatively micro your Dolls to avoid this Damage, or use HP shields to soak the Damage. 

3rd Phase: If the fight goes too long, the boss will start dealing massive AoE damage that you cannot survive. If this happens, retreat your Echelon to save your repair bills and then run back to finish her off. 

Don't feel bad if the fight takes a few tries to pull off, it can be rather chaotic on the first attempt.

Turn 1


Deploy a Combat Echelon on the Command Post. Swap with Yurine and move right two nodes. 


Yurine will move down one node. End your turn.

Turn 2


Move your Combat Echelon up one node, and deploy a Dummy Echelon on the Command Post. This will allow us to save AP next turn while not triggering additional battles.

Turn 3

Move the combat Echelon up 3 nodes. This will expose the map. If you can see Ouroboros, proceed, otherwise reset now. 


We can see Ouro, so let's proceed. 

Have Ouroboros use her Strategy Skill on the 80k Dog to her left. This will prevent it from moving. 


Move your Combat Echelon to the right one node. 


Move Ouro down one node. End your Turn.

Turn 4


Move Ouro down four nodes. This will prevent the Dog on Alert AI from moving into your path next turn, while Yurine goes to eat the Ice. You can also run and kill the boss now if you wish to forgo the Achievement.

Turn 5


Move your Combat Echelon to the left one node, up one node, right once, up and then right again to engage the boss. Repeat this process as needed if you take multiple swings at the boss.
