Parafrosini

Parafrosini is the final boss of the Underground Grove. She prefers using her pheromone attacks to weaken the player, before finally delivering the finishing blow. Unlike the other succubi encountered so far, she seems to be almost maniacal, taunting the player the moment he enters her lair.

Strategy
Parafrosini is probably the trickiest fight the players will have faced yet. A read through the combat guide is highly recommended. In addition, it's important to be aware that you can target her relic, and are by default. The relic provides her a powerful buff, but it can be smashed if hit twice with Pommel Strike.
