Berkut GHB One Turn Clear (OTC) - Infernal

Team Comp: Dancer, Camilla, Cordelia, Dancer

Inspired by /u/ptolemy77's Lunatic version, I adapt a similar strategy to work for the Infernal difficulty. In this guide, you will learn how to clear Berkut's grand hero battle on infernal difficulty, in a single turn! I have broken it down with a video, step by step with screenshots and full character builds you can paste into the KageroChart combat simulator.

Berkut GHB One Turn Clear (OTC) Video - Infernal

Combat Log

In the video I used merged units since I don't have the extra units to do make an unmerged team. The actual setup and execution for a pure unmerged team without Hone Fliers is slightly different than that seen in the video, but not by much.

Builds

Camilla

Camilla

Camilla [Neutral]
37 HP / 44 ATK / 32 SPD / 23 DEF / 26 RES
Weapon: Brave Axe+
Special: Galeforce
Passive A: Life and Death 3
Passive C: Savage Blow 3
Sacred Seal: Attack +1

Notes

I was asked to provide a setup that doesn't require Hone Fliers, so this was the best that I could come up with. Life and Death is needed for both the ATK buff and DEF debuff. The ATK buff allows her to kill Berkut while the DEF debuff allows her to fall below 50% to activate Wings of Mercy 3 on the dancers.

Savage Blow 3 is a very economical alternative to the usual tactic of adding Spur Atk to a dancer.

Any nature should be workable barring ATK bane or DEF boon.


Cordelia

Cordelia

Cordelia [Neutral]
40 HP / 43 ATK / 30 SPD / 22 DEF / 25 RES
Weapon: Brave Lance+
Special: Galeforce
Passive A: Death Blow 3
Passive B: Lancebreaker 1
Passive C: Goad Fliers

Notes

Lance Breaker 1 is needed to double the Lance Cavalier unless you can buff Cordelia's speed by 2 (Hone Spd/Fliers).

Goad Fliers allows Cordelia to buff Camilla for the extra stats she needs to finish off the non-blues.


Dancers

Any 2 dancers. Just make sure both have WoM. (Cordelia will drop lower, below WoM 1 range usually).
