How to clean a Dungeon

Your wizard master has instructed you to clean the old Dungeon and only equipped with the little magic you know, you better try your best to use the tools and CHAIN REACTIONS down there to get all the cobwebs, magical mishaps and rats out. But be careful, you dont destroy any books, the wizard hates that. Use you mouse to channel the power of the most basic energy blast or teleportation-mirror-activation spells, only limited by the 3 mana you have.
