Estelle had been a bit more quiet ever since they got into the dungeon, it was just the perfect time to keep a good look at each one of her companions. Sadly outside of an odd stare at her body it was mostly talk about god and heaven which was on the boring zone for her, after all, divination was a skill that took a bit of the glim of divinity. 

A bit later they ended up walking in the center of the problem, things took a quick turn and she had difficulty understanding what the hell just transpired, nevertheless she quickly turned her Trickster back into a sword and prepared herself to fight enemies...

A piercing weapon like hers was obviously bad against bones, trying to eliminate the skellies herself would be silly, good thing that many of them were carrying weapons and by disarming them (in both senses) she could be of help to the team. Gracefully she stepped into the fight, quickly intercepting an enemy sword before it finished slashing, from there onward the movement was easy, the skeleton would bring its sword back giving her plenty of time to pierce the wrist, incapacitating it for a while. 

After repeating the process a bit more she finally took notice of the altar and of the people trying to break it. "Uh, why don't you soak it in holy water? It will probably jam the magical effect"
