Concubine Special Achievement
Defeat the Concubine without using grab.
The grab button is the button, avoid this one during the first fight with the Concubine. The concubine is the only female boss of the 4 bosses and probably the most annoying because of her comments. Elika will tell you her name so you’ll know when to try for this achievement.
This achievement can be unlocked in any of the battles with the Concubine.
