After sometime when Helena felt that she had exchange enough attacks with the witch, she approached her with a sword in her hand.
And at this time, the witch had collapsed to the ground with multiple injuries all over her body. Even one of her arms had ripped away with blood spurting without stop from it.
Then with a swing of her blade, the witch's head cut off from the neck and shot into the air before crashing into the earth many feet away.
After Helena slashed off her head, she went into the shrine with her friends to rescue the little kids that were kept captives in there.
When they released the children with Helena's friends leading them out, Helena casted a powerful fire spell on the shrine which actually materialized into an inferno-sized flame in the next instant and then began to burn the shrine.
Then when she came out after casting the fire spell, she followed behind the kids who were being led to the kingdom by her friends.
