You run up to the skeletons and stab a few. The other skeletons come to investigate, but it's too late you've already lit the TNT.
You defeat all the skeletons and collect a fully used bow, and a stack and a half of arrows
You keep exploring and find a regeneration potion and drink it. You're now back to full health! You keep walking until you come to the end of the hall.
You open the door and walk in the room, there a witch is sitting on a chair surrounded by potions, chuckling. You are confused, because most witches wear purple, but not her, she was wearing yellow. Then you remember, there was only one witch that wore yellow: Lady Digona, the most powerful witch ever. She rises from her desk and turns around, and starts throwing potions at you. What do you do?
Shoot with bow
